Which one of the following words is opposite in meaning to Alleviate?

Aggravate

The correct answer is Option (2) → Aggravate

"Alleviate" means to make something less severe or to relieve. The opposite is "aggravate," which means to make a situation or condition worse or more severe.

Option (1) → Exaggerate: Means to represent something as greater or more extreme than it really is. It relates to overstating, not directly to making something worse in terms of pain or difficulty.

Option (3) → Relieve: Means to reduce or remove pain or difficulty, which is a synonym of "alleviate," not its opposite.

Option (4) → Lighter: Means less heavy or less serious, which can imply some form of alleviation, but it is not the exact opposite of "alleviate."
