Solution

The correct option is D
none of these

In the given velocity-time graph, AB shows that the body has

Acceleration is defined as rate of change of velocity,

acceleration = $\frac{c h a n g e i n v e l o c i t y}{t i m e}$

In the above case, the velocity of the body doesn't change with time, hence the body is not accelerating or decelerating. The body has a particular initial velocity, let us assume the initial velocity to be v. The body continues to move with this velocity.

Hence the correct answer is 4.
