Correct: "Each will reflect at an angle equal to its angle of incidence."
Explanation: The law of reflection (angle of incidence = angle of reflection) still holds at each point on the bumpy surface, but the local surface normal changes from point to point. That means the reflected rays generally go in different directions (diffuse reflection). The other statements are false: the law of reflection is not violated, they will not all reflect at the same angle unless the surface is flat (or the local normals are all the same), and they will not all travel in the same direction.
