The initial horizontal component of the vector which represents the velocity of the ball is; Choice C; 11.4 ft./sec.

What is the horizontal component of the ball's velocity?

It follows from the task content that the velocity vector of the ball has magnitude 15.8 ft./sec. and is at an angle of 43.8° with the horizontal.

On this note, it follows from vector resolution that the horizontal component of the ball's velocity is;

V(x) = V cos 43.8⁰

V(x) = 11.4 ft./sec.
