Change the following sentence into Direct Speech: I asked him where he would stay.

I said to him “Where will I stay?”

I said to him “Where you will stay?”

I asked him “Where will you stay?”

None of these

I asked him, “Where will you stay?”

In direct speech, the pronoun and tense are adjusted: "he would stay" becomes "you will stay."

Since it's a question, the correct form uses "will" before the subject.
