Select the most appropriate ANTONYM of the given word.
Contaminate
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Purify.
Contaminate means “to make something impure or dirty, especially by adding harmful substances.”
The opposite of making something dirty is purifying it — making it clean or free from impurities.
Option 1 (Extract): Means to take something out; not the opposite of contaminate.
Option 3 (Collect): Means to gather; unrelated to cleanliness or impurity.
Option 4 (Pollute): Has the same meaning as contaminate, so it’s a synonym, not an antonym.
