Correct option is B)
The acceleration vector is always in the horizontal direction for any point on the disc. The velocity of point P is composed if two components- one in the horizontal direction and the other in the vertical direction perpendicular to the radius. Both of these are equal to v and thus their resultant is2 v at an angle of 45 0
to the horizontal. Thus we get the angle between the velocity and the acceleration vectors.
