c) the low ph and high acidity of vinegar destroy bacteria.

Explanation:

Vinegar contains acetic acid which is preferred as a preservative in foods because it is expected to lower the pH of the food. As a result of this many microorganisms are incapable for surviving in such acidic pH. Otherwise the microorganisms like bacteria can contaminate the food and can make the food unfit for consumption.
