6 Don’t get angry, I promise you it wasn’t me who stole your money. You’re _____! 1. a fish out of water 2. on cloud nine 3. down to the wire 4. barking up the wrong tree

Answer 1

heya,

 Don’t get angry, I promise you it wasn’t me who stole your money. You’re barking up the wrong tree! 

reason : Barking up the wrong tree means to shout/scold a person who is not the defaulter of that mistake.

Here, the meaning of sentence is that dont get angry on me. I promise it you it wasn't me who stole your money.you are blaming or shouting on a wrong person. I am not that.
So, it is the right option.

thank you!
