Compared to falling on a stone floor, a wine glass may not break when it falls on a carpeted floor because the?

A.carpeted floor provides a smaller impulse.
B.stopping time is shorter on the carpet.
C.stopping time is longer on the carpet.
D.carpet provides a smaller impulse and a longer time.

It’s not D.

Impulse is F*t. That’s what it’s not D. The carpet provides a longer time which cuts down on the force not the impulse. So what I’ve described is C.

That eliminates B You cannot be sure about A, since the time is longer the force may be less. You just cannot can’t be sure.
