Correct Answer
B. If..elseExplanation
The correct answer is if..else. The ternary operator can be used as a substitute for an if..else statement in certain cases. It provides a concise way to write conditional statements and allows for a more compact code. The syntax of the ternary operator is "condition ? expression1 : expression2", where the condition is evaluated and if true, expression1 is executed, otherwise expression2 is executed. This makes it a suitable alternative to if..else statements when there are simple conditional checks that need to be made.Rate this question:
