Answer:

c) citric acid is the right answer

Explanation:

Answer 2

Spoilage of food can be avoided by the use of citric acid.

Explanation:

• When food is exposed to air for a longer period of time then micro-organisms and bacteria present in the air get deposited on the surface of food. As a result, the bacteria gets multiplied due to which a rotten smell occurs after sometime.

• When food is spoiled then there will occur a change in its color and appearance as compared to the fresh food. Due to these changes the spoilage of food can be easily detected.
