Topic: Pair of Word,

Best Answer Explained in Below-:

The sentence "No one can __ that he is clever." requires a word that fits logically into the context of making a statement about someone’s intelligence. The correct answer is "A) Deny."

To "deny" means to refuse to acknowledge or accept the truth of something. In this context, if someone claims that a particular person is clever, saying that “no one can deny” implies that the cleverness is evident and indisputable. Thus, it suggests that observers recognize this person’s intelligence, making it impossible for anyone to credibly refute that claim.

On the other hand, the other options do not logically fit into the sentence based on their meanings:
- B) "Defy" means to openly resist or refuse to obey and does not apply in terms of acknowledging intelligence.
- C) "Denounce" means to publicly declare something to be wrong or evil, which also doesn't fit the context of acknowledging someone's cleverness.
- D) "Discard" means to throw away or get rid of and is not relevant to recognizing or commenting on someone's intelligence.

Therefore, "deny" is the appropriate word that aligns with the idea of universally acknowledging the cleverness of the individual in question.
