E) False.

Explanation:

When a body is thrown in upward direction, it accelerated in downward direction and not in upward direction. It is so because, force of gravitation acts in downward direction.

Even if some invisible force pulls it in upward direction, it may have an acceleration in upward direction. In case it accelerates in upward direction, it will never stop so its maximum height will lie at infinity. In this way, the statement appears to be false.
