If the velocity is decreasing, the object is decelerating.
Decelerating means to slow down. It means that an object is moving at an increasingly slower speed.
Decelerating means that the speed, i.e., the absolute value of the velocity, decreases over time.
c is correct.
It means the object is decelerating - slowing down rather than speeding up. You can think of it as negative acceleration.
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
The object is accelerating or decelerating in the radial direction.

decelerating
The object is accelerating or decelerating in the radial direction.
It now lacks acceleration and is either maintaining constant speed or is decelerating.
Yes. That is what the term deceleration means.
c. Free fall
c is correct.
It is decelerating any time it is not accelerating or is stopped. Decelerating means slowing down.
