Solution
The correct option is A Due to inertia of dust
The inertia of an object tends to resist any change in its state of rest or state of motion. When a carpet is beaten with a stick, then it comes in motion. But, the dust particles try to resist a change in their state of rest. According to Newton's first law of motion, the dust particles stay in a state of rest, while the carpet moves. Hence, the dust particle comes out of the carpet due to inertia.
