Correct Option: B

Vacuum cleaners work by creating a lower pressure just inside the opening which touches the floor. By creating a low pressure inside the machine, higher air pressure in the room pushes its way into the vacuum cleaner, taking the dirt with it. Because there is no, or very little, atmosphere on the moon, we can’t create a lower or higher gas pressure inside and outside the machine, so dirt cannot be sucked up from the ground. Nothing happens when a vacuum cleaner is turned on the moon.
