Correct option is C
Given:
AB is the diameter of the circle with center O. ∠AOP = 95°.
Formula Used:
Since ∠AOP is an angle subtended by the diameter, the angle at the circumference subtended by the same arc is half of ∠AOP.
Solution:

Since AB is the diameter, ∠AOP = 95°
triangle OBP is a s implies ∠OBP = ( Because ∠OBP is the exterior angle of triangle OPB and OP = OB both are the radius of this circle so ∠OPB = ∠OBP)
∠OPB+ ∠OBP = 95°
∠OBP =
∠OBP = 47.5°
