Answer: D
In such question, we might take a look at the picture and see AB is bigger than OA and OB. Thus B is considered to be bigger.
The best way here is drawing a new circle which in that Angle AOB is too small then we will see that OA is bigger than AB and A is the answer. Also Ab can be equal to OA if all of the angles in the rectangle are 60 degrees, then C will be the answer.
So all of the options might be true and we can’t construe based on this shape without enough information.
The answer is D

Refer the attached figure..
We do not know the position of B..
(I) let B be at 90 degree with AO, then AB is the hypotenuse of right angled triangle AOB and will be > AO, as Ao is a leg and AB is the hypotenuse
(II) let B' be at 10 degree and radius is as shown, clearly AO>AB..
so insufficient
D
