Solution

The correct option is B

50


Note that OA = OB=radius of the circle.
Since angles opposite to equal sides are equal, OAB=OBA=40.
Using angle sum property in OAB, we have
AOB=180(40+40)=100. 
Since the angle subtended by an arc at the centre is double the angle subtended by it at any remaining part of the circle, we have
ACB=AOB2=50.
