Aparachute works because the canvas of the parachute is acted upon by
a. inertia
b. gravity
c. velocity
d. momentum

I beleive the answer is: A. Inertia

Inertia is resistance of any physical object to any change in its position and state of motion. When a parachute is spread, the gravity would drag the body of the parachute user downward, and at the same time a drag force upward would be created even though it wouldn't be as strong as the gravity force.
