Choose the most appropriate option to change from an Assertive to an Exclamatory sentence :

I wish I had the wings of a bird.

If only I had the wings of a bird!

The most appropriate option to change the assertive sentence "I wish I had the wings of a bird" to an exclamatory sentence is If only I had the wings of a bird!.

An exclamatory sentence expresses a strong emotion, such as surprise, excitement, or anger. The use of the exclamation mark (!) emphasizes the strong emotion. The other options are not as emphatic or expressive of emotion.
