Acceleration is defined as the rate of change for which of the following
a. time
b. velocity
c. position
d. displacement

The acceleration of the body is defined as the rate of change of velocity.

Further Explanation:

The body is said to be accelerating its velocity is changing with the time. The velocity of a particular body is defined as the rate of change of displacement of the body.

The velocity of a body is represented as:

Here,  is the position of the body and  is the time

Now when a body moves with a constant speed during its motion, then it is considered as the uniform motion of the body. During the uniform motion of the body, the acceleration of the body remains zero.

But if the velocity of the body is changing along with the time, the body is said to be accelerating. The acceleration of the body is defined as the rate of change of velocity of the body. It is represented mathematically as:

Thus, the acceleration of the body is defined as the rate of change of velocity.
