_________________________

I understand that the word"waver"is someone who waves, and the word"waiver" means to relinquish something. From the context "waiver" should be the right answer.

No, waver is the right answer and is a verb that means hesitate. Waiver is a noun and comes from the verb waive meaning abandon or let pass.
