Correct Answer - A::D
Area under a-t graph gives us change in velocity. From this, it can be inferred that the velocity changes by more than 7 m/s, so it has to be zero once before the particle changes its direction of motion, also displacement of the body cannot never be zero as the particle continues to move further.
