If you draw a line from O to D, you get an isosceles triangle (since OD and OA are the same length).
So, angle OAD = angle ODA (both 65 degrees)
That means, the angle opposite arc AD is 50 degrees (180 - 65 - 65 = 50). So, arc AD > arc CB

Join Line OD
OA =OD = Radius of circle
So In triangle OAD
Angle A = Angle D = 65 degree
remaining angle AOD = 50 degree

Angle BOC =40 degree

So the arc will be bigger in A. Hence the answer is A.

For \(\triangle\) AOB, AO=OD = Radius and

hence the \(\angle\) oad = \(\angle\) oda = 65

therefore central angle = 50

**Greater the central angle, greater is the arc length

central \(\angle\) AOD > central \(\angle\) COB

Hence option A

Carcass sir, suppose 65 degree is not mentioned in the figure then we would consider angle of arc AD as 40 degree as vertically opposite angle or is there is any condition when two angles can be called vertically opposite ?

As you stated in your question, yes we could consider the other angle as 40° but it all depends also on the information in the question or figure
