Appeared in: UPUMS Nsg officer-2023

Explanation

The question requires finding the antonym (opposite) of the word 'pure'.
'Pure' signifies something that is unmixed, clean, and free from any contaminants.
'Adulterated' means to degrade the quality of something by adding an inferior or harmful substance, making it impure.
Therefore, 'adulterated' is the direct opposite of 'pure' in meaning.

Option A: This word refers to the price (expensive) of an item, not its quality or composition.
Option B: This word is a synonym (has a similar meaning) of 'pure', not an antonym.
Option D: This word refers to the price (inexpensive) of an item, not its quality or composition.
