(i) He said to him, “why do you waste your time?”

Asslamulaikum,

Dear Shallow water, Me and you both have committed mistakes in my and your's previous posts.
If in reporting speech we use "Ask", Interrogative sentence, then in reported speech Question is not repeated as you did!!
The exact order is!
He asked him why he wasted his time.

Regards.
