Choose the word which is different from the rest.

The answer is D. Depend.

The other three words (A, B, and C) are all synonyms for “to acknowledge or declare something that is true, especially something that is unpleasant or embarrassing.” Depend, on the other hand, means “to rely on or trust someone or something.”

For example, you might say “I admit that I was wrong” or “I confess that I stole the cookies.” However, you would not say “I depend that I was wrong” or “I depend that I stole the cookies.”
