**(b)**

Angular momentum (Linear momentum) (perpendicular distance to line of motion

from the axis)

or angular momentum is moment of momentum. Here, the angle goes on decreasing from but the perpendicular distance to the line of motion remains constant. Therefore, angular momentum is also constant (linear momentum is constant).
