Answer:

Explanation:

When the downward force of gravity on a falling parachutist is exactly equal to the upward force of air resistance , net force on the parachutist will be zero . As a result of it , there will be no acceleration in his downward motion . In other words , his downward velocity will not be either increasing or decreasing . It will remain steady .

So option b) is correct.
