Solution

Dear student,
Preservatives are used to delay spoilage, enhance colour and flavour, and maintain consistency and texture of foods.
Sodium benzoate inhibits the growth of bacteria and yeast in acidic condition.
This is most commonly used in fruit juices, pickles and carbonated beverages.
So the answer is (4) Sodium benzoate
