Which word is an antonym of 'validate'?

• A. Prove
• B. Confirm
• C. Invalidate
• D. Support

Answer: (C)

Antonyms are words with opposite meanings. Validate means to confirm that something is true, acceptable, or legitimate. It’s about giving approval or making something officially correct. The opposite of that is to render something invalid or not true. A word that captures that opposite idea is invalidate, which means to discredit or deny the validity of something. The other options—prove, confirm, and support—are all ways of showing that something is valid or true, so they don’t express the opposite of validate. Therefore, invalidate is the best choice.
