Concept:Antonyms are words with opposite meanings. ‘Affirm’ means to state something as true or to confirm strongly. Its opposite is to deny, reject, or say no.
Explanation:‘Affirm’ means to assert or confirm (पुष्टि करना). ‘Refuse’ means to decline or reject (इंकार करना). So ‘refuse’ is the direct opposite.
Other options are not antonyms:
- ‘Accept’ means to agree to receive, which is similar to affirming.
- ‘Acknowledge’ means to recognize the truth, also similar.
- ‘Support’ means to assist or back, which is consistent with affirming.
Thus, only ‘refuse’ gives the opposite meaning.
Answer:Refuse (Option A)
