Answer: If I were a dove, I would have wings.
Explanation:
A subjunctive verb is a special type of present tense verb that is usually used in a manner that isn't factual or is doubtful.
In this sentence, the speaker is not a dove, the speaker is saying if he/she was a dove, they would have wings. Because of that, the notion that he has wings isn't factual and is doubtful.
None of the other sentences exhibit this in their verbs or mood so that only leaves "if i were a dove, I would have wings" as the answer.
I hope this helps!
