Selitys
Motion of the particle is shown below

Initially speed of the particle is maximum(v0) and at heigth h velocity will become zero, then particle will move downward and velocity will increase gradually and become maximum when it reaches the ground. And acceleration in this entire motion will be -g, so slope of v - t will be same and negative.
So only Option (D) will be correct.
