A body A is dropped froma a height $$h$$ above the ground. At the same time another body B at a distance $$d$$ from the projection of A from the ground is fired at an angle $$\alpha$$ to the horizontal. If the two collide at the maximum point of the trajectory of B the angle of the projection is given by

(A) $$\alpha = \tan^{-1} \left( \frac dh \right)$$

(B) $$\alpha = \sin^{-1} \left( \frac hd \right)$$

(C) $$\alpha = \tan^{-1} \left( \frac hd \right)$$

(D) $$\alpha = \cos^{-1} \left( \frac hd \right)$$
