Water : P :: Food : Q Choose the P and Q combination from the options below to form a meaningful analogy.

The analogy represents the relationship between a consumable item and the physiological sensation/need it relieves or satisfies:

• Water relieves Thirst ($P = \text{Thirst}$).

• Food relieves Hunger ($Q = \text{Hunger}$).

Thus, the relationship is consistent in both pairs.

Therefore, option A is the correct choice.
