A body is trown vertically upward with velocity, the greatest height to which will rise will be, a) always less than 1, b) always equal to 1, c) always more than 1, d) equal to less than 1?

c) always more than 1

The greatest height reached by a body thrown vertically upward will always be more than 1, as long as the initial velocity is greater than 0. This is because the body will continue to rise until its velocity becomes 0 at the highest point, before falling back down due to gravity.

c) always more than 1
