Vinegar can be made from apples because apples contain natural sugars that can be fermented into alcohol, and then further fermented into acetic acid, the main component of vinegar. This process involves crushing the apples to extract their juice, which is then fermented with yeast to convert the sugars into alcohol. The alcohol is then exposed to oxygen, allowing bacteria to convert it into acetic acid, resulting in vinegar.

  Fermentation
- B.
  
  Preservation
- C.

  None of the above
Correct Answer
A. Fermentation

Explanation
Vinegar can be used for fermentation because it contains acetic acid, which acts as a natural preservative and helps convert sugars into alcohol. During fermentation, bacteria or yeast convert the alcohol into acetic acid, resulting in vinegar. This process is commonly used in the production of various fermented foods and beverages, such as pickles, sauerkraut, and wine. Therefore, vinegar is a suitable ingredient for fermentation purposes.
