Geometry Level pending

Two circles intersect at $$P$$ and $$Q$$. $$AD$$ is a line drawn meeting the circles as in the given figure. Then

(A) $$\angle APB + \angle CQD = 90^\circ$$.
(B) $$\angle APB + \angle CQD = 180^\circ$$.
(C) $$\angle APB = \angle CQD$$.
(D) $$\angle APB - \angle CQD = 90^\circ$$.
