I think the question is wrong. Sorry if I am wrong!
But It should have been "You cannot get a refund ________ sale goods."
In this case the answer should have been ON.

Testimonial evidence is a statement made under oath. An example would be a witness pointing to someone in the courtroom and saying, “That's the guy I saw robbing the grocery store.” This is also called direct evidence or prima facie evidence. Physical evidence can be any object or material relevant in a crime.
