The Figure Represents the Parabolic Trajectory of a Ball Going $\theta$

Multiple Choice

The figure represents the parabolic trajectory of a ball going from a to e in Earth gravity but without air resistance. The initial velocity of the ball is V_o at an angle $\theta$ to the horizon. The vertical dashed lines represent equal time interval, $\Delta$ t. The horizontal velocity at point c is

A) 0.
B) V_o cos $\theta$ ) .
C) V_o sin $\theta$ ) .
D) V_o.
E) depends on what g is along the path.
