Answer Key / Explanation : (b,d) -

(b,d)

When the particle just reaches the top of the wedge

    (i)

Apply conservation of energy

Solve to get

Angle of projection w.r.t. wedge. But angle of projection as observed by the ground will be less than  because horizontal component velocity will be more in this case
