A projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one sixth as large. How does the maximum altitude of the projectile on the Moon compare with that of the projectile on the Earth? 

(a) It is one-sixth as large. 

(b) It is the same. 

(c) It is 6th times larger.

 (d) It is 6 times larger

 (e) none of (a), (b), (c) and d)
