Answer 1

The correct option is D All of the above

Salts and edible oils are the common chemicals generally used to check the growth of microorganisms. Therefore, they are called preservatives. We add salt or acid preservatives to pickles to prevent the attack of microbes. Sodium benzoate and sodium metabisulphite are common preservatives. These are also used in the jams and squashes to check their spoilage.
