  4. (a)- (iv), (b)- (iii), (c)- (i), (d)- (vi), (e)- (ii)

Show answer
Correct Option: B
Explanation:

Amla is a seasonal fruit, so we can preserve amla for 6 months in salt. Typical pickling agents include brine (high in salt), vinegar, alcohol, and vegetable oil are added to preserve vegetables. When making squashes, we make use of acetic acid and a lot of sugar for preservation. Air-drying is a method to preserve herbs and spices. Boric acid, benzoic acid and sodium benzoate, were once widely used as preservatives in ketchup. Thus, the correct answer is option B.

Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. The concept of food additives being "generally recognized as safe" was first described in the Food Additives Amendment of 1958, and all additives introduced after this time had to be evaluated by new standards.

Therefore, the correct answer is option B.
