Match List-I with List-II:
List-I (Chemical Compound)                                 List-II (Used as)
a. Sucralose                                                     i. Synthetic detergent
b. Glyceryl ester of stearic acid                       ii. Artificial sweetener
c. Sodium benzoate                                        iii. Antiseptic
d. Bithional                                                    iv. Food preservative
Choose the correct match:

Let us match each compound with its use.

(a) Sucralose is a chlorinated derivative of sucrose and is widely used as an artificial sweetener. It is about 600 times sweeter than sugar but contributes no calories. So (a) matches with (ii).

(b) Glyceryl ester of stearic acid is glyceryl monostearate, which is used in making soaps and synthetic detergents. It acts as a surfactant. So (b) matches with (i).

(c) Sodium benzoate ($$\text{C}_6\text{H}_5\text{COONa}$$) is a well-known food preservative. It is commonly added to acidic foods like pickles, fruit juices, and carbonated drinks to prevent microbial growth. So (c) matches with (iv).

(d) Bithionol is a phenolic compound that is used as an antiseptic, particularly in medicated soaps and other personal care products. So (d) matches with (iii).

The correct matching is (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii), which is Option B.
