"Difference between" is the correct fixed expression because "between" is used when comparing two or more distinct things — in this case, formal and informal registers. "Difference of" is used in mathematical contexts to describe the result of subtraction, not a qualitative comparison. "Difference at" is not a standard prepositional pairing with "difference" in this context. "Difference about" is not a recognized fixed expression in English.

"Kind of you to" is the correct fixed expression used to acknowledge someone's generosity or helpfulness, following the structure "it was [adjective] of [person] to [verb]." "Kind for you to" is a common error but is not standard; "for" is used in purpose clauses rather than to attribute a quality to a person. "Kind by you to" is grammatically incorrect and not a recognized English expression. "Kind from you to" is also non-standard and does not follow the established pattern for this type of compliment.

"In" is the correct preposition because "drop in" is the standard fixed expression used when describing a decrease in a measurable quantity or condition, such as consumer confidence. "Of" indicates possession or belonging and does not form a standard collocation with "drop" in this context. "For" indicates purpose or benefit, which does not fit a statistical decline. "At" indicates a specific point or location and does not collocate with "drop" when describing a decrease.

"Invitation to" is the correct fixed expression because "to" indicates the event or destination toward which the invitation is directed. "Invitation for" is sometimes used informally but is not the standard preposition in formal written English when referring to a specific event. "Invitation at" is grammatically incorrect as "at" refers to a location rather than completing the noun phrase. "Invitation of" implies possession rather than directing the invitation toward an event.

"In connection with" is the correct fixed prepositional phrase meaning in relation to or as part of an investigation into something. "In connection to" is a common error but is not standard in formal or legal English. "In connection of" is grammatically incorrect and not a recognized expression. "In connection by" is not a standard English phrase and has no established usage in this context.

"Excuse for" is the correct fixed expression because "for" introduces the thing being excused or justified, following the standard collocation "no excuse for." "Excuse to" is used when followed by an infinitive verb, as in "an excuse to leave," not when referring to a behavior or act. "Excuse of" is not a standard prepositional pairing with "excuse" in this context. "Excuse about" is not a recognized fixed expression in English.

"Solution to" is the correct fixed expression because "to" is the standard preposition that links "solution" to the problem being addressed. "Solution for" is occasionally used informally but is not the preferred form in professional or academic writing. "Solution of" is used in scientific contexts to refer to a liquid mixture and does not apply here. "Solution about" is not a recognized collocation in standard English.

"Attitude toward" is the correct fixed expression because "toward" indicates the object or subject of someone's attitude, which is the standard preposition in both British and American English. "Attitude of" indicates possession — as in "the attitude of the employee" — rather than what the attitude is directed at. "Attitude about" is used informally but is not the preferred form in professional contexts. "Attitude for" is not a standard prepositional pairing with "attitude" in this sense.

"Angry about" is the correct fixed expression because "about" introduces the subject or cause of the anger, which is the standard preposition following "angry" when referring to a situation or circumstance. "Angry at" is used when the anger is directed at a specific person rather than a situation. "Angry over" is used informally in some dialects but is not the preferred standard form in professional written English. "Angry on" is not a recognized prepositional pairing with "angry" in standard English.

"Reaction to" is the correct fixed expression because "to" introduces the stimulus or event that prompted the reaction. "Reaction about" is not a standard collocation in formal English. "Reaction of" indicates possession — as in "the reaction of the board" — rather than what the board was reacting to. "Reaction on" is not a recognized prepositional pairing with "reaction" in standard usage.
