I. Viscous force is proportional to the velocity of the object.
II. Viscous is a dragging force which acts opposite to the direction of motion.

III. Viscous force depends on viscosity \( \eta \) of the fluids and radius \( r \) of the sphere.
Which of following statement(s) is/are correct?
(a) Only I
(b) Both I and II
(c) Only III
