Find the mistake: I would love (A)/ to be able to swim (B)/ if I am not afraid (C)/ of water (D)

Explanation

The verb tense in "if I am not afraid" is wrong. Although the rest of the sentence is in the conditional mood, which expresses hypothetical or ambiguous circumstances, the verb "am" is in the present tense. We employ the past tense version of the verb "to be" (i.e., "were or was") rather than "am" to indicate hypothetical circumstances in the present.
