Question

please answer this with explanation ​

Answer 1

(Acceleration = Velocity/Time)

According to this graph,

the body was accelerating at a constant rate, so velocity was also increasing with time. After reaching a certain velocity, the body started decelerating its motion at a constant rate, because the dotted line joins the same velocity on the either side at the same point on the X-axis. So the velocity was also decreased with time until it's motion came to a stop. So Option A is the correct answer.
