Anyone knows why is the ans B?
If you raw a line from B to C, you get triangle CBD
area CBD = area EBD (because they are congruent SAS)
area of shaded region = area CBD + something positive = area EBD + something positive
Thus, area of shaded region > area EBD

Can you pls share a nice article explaining congruency rules SAS etc?
Well you can do this particular question without congruency as well
area CBD = area EBD = 1/2 * BD * (ED = CD = r/2)
But for congruency:
