A particle is aimed at a mark which is in the same horizontal plane as that of point of projection. If falls 10 m short of the target when it is projected of an angle of 75° and falls 10m ahead of the target when it is projected with an elevation of 45°. The angle of projection for which the particle exactly hits this target is (g=10ms^-1)

A. (1/2)sin^-1 (3/4)

B. (1/2)sin^-1 (4/5)
