While dusting a carpet, we give a sudden jerk or beat it with a stick, because

(a) Inertia of rest keeps the dust in its position and the dirt is removed by the movement of carpet away

(b) Inertia of motion removes the dust

(c) The jerk compensates for the force of adhesion between the dust and the carpet and the dust is removed

(d) None of the above
