The correct answer is "retard the motion of the body."

Explanation: A retarding force acts in the opposite direction to the motion of a body, causing it to slow down (retard).

It does not:
- "change the motion of the body" in a general sense (unless specified, as retardation is a specific type of change).
- "introduce the motion of the body" (since it opposes motion rather than initiating it).
- "none of these" is incorrect because the retarding force does indeed retard motion.

According to me, the correct answer is "C".

I think option C is correct as all others are related to retarding force.

@Alok,

Retard doesn't mean work. It means to reduce the motion of something. Option C should be the right answer.

Answer must be option (c).

Retarding force produces -ve acceleration.

So this force reduces velocity and finally 0 velocities.
"Retard" mean "work"
So Retarding force does not retard the motion of the body.
