Suppose $A B C D$ is a quadrilateral such that $\angle B A C = 50 ^ { \circ } , \angle C A D = 60 ^ { \circ } , \angle C B D = 30 ^ { \circ }$ and $\angle B D C = 25 ^ { \circ }$. If $E$ is the point of intersection of $A C$ and $B D$, then the value of $\angle A E B$ is\\
(a) $75 ^ { \circ }$.\\
(B) $85 ^ { \circ }$.\\
(C) $95 ^ { \circ }$.\\
(D) $110 ^ { \circ }$.
