Best answer
The correct option is (a) 0

The best explanation: Angle of repose is defined as the steepest angle of descent or dip. It is with relation to the horizontal plane to which a material can be piled. The minimum value for angle of repose is zero degrees. It lies on the horizontal surface. Therefore, there is no sliding.
