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
