Only the right ! which is the best definition of rebuttal? a.an opposing side of the author’s argument or viewpoint b.a statement of a viewpoint that supports one side of an argument c.an explanation of why an opposing argument is false d.a personal opinion or judgment that is not backed by evidence

C. an explanation of why an opposing argument is false

Explanation:

Rebuttal is the act of refuting something by making a contrary argument, or presenting contrary evidence.

If you make a rebuttal of a charge or accusation that has been made against you, you make a statement which gives reasons why the accusation is untrue.

Therefore, the best definition of rebuttal is the third choice (an explanation of why an opposing argument is false).
