Assuming no air resistance, the answer would be C

Explanation:

The thing to note is when the projectile reaches it's highest point, it has lost all of its vertical velocity.

The vertical velocity of this projectile is #usintheta# and since the projectile loses this velocity, it would have a difference of #usintheta#
