Which one of the following statements for an object falling freely under the influence of gravity is correct?

Zero acceleration always implies zero velocity

Zero acceleration has no relation with the velocity of the object

Zero velocity at any instant necessarily means zero acceleration at that instant.

Acceleration is constant throughout the free fall.

Explanation:

The sign of acceleration cannot determine whether the particle’s speed is increasing or decreasing. The sign of acceleration depends on the choice
of the positive direction of the axis. For example, if the vertically upward direction is chosen to be the positive direction of the axis, the acceleration
due to gravity is negative. If a particle is falling under gravity, this acceleration though negative results in an increase in speed and it is constant throughout the free fall.
