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 longing. The exclamation mark (!) emphasizes the emotion. The other options are not as expressive.
