$A$ body is thrown vertically upwards with a velocity $u$. Find the true statement from the following:
- ABoth velocity and acceleration are zero at its highest point.
- BVelocity is maximum and acceleration is zero at the highest point.
- CVelocity is maximum and acceleration is $g$ downwards at its highest point.
- DVelocity is zero at the highest point and maximum height reached is $u^2 / 2g$.
