Answer is D

Here is the explanation :

Since AB = OC, which is the radius of the circle --> AB = BO, so we have 2 iscoceless traingles, ABO and BOC.
Lets say angles BAO is y, ACO is x.
From option 1: since angle COD is 60, x+y = 180-120= 60
And 2y+180-x = 180for triangle ABO
2y = x
3y = 60
y =20

From option 2 :
x = 40 degrees

From triangle ABO, 2y +180-x = 180
2y = x
so, y = 20

So the answer is D.
