Detailed Solution

The above statement is false.
Moon orbit earth in an elliptical path and moves with some velocity. Due to this moon's motion, it experienced a centrifugal force directed outward, and the gravitational force between the earth and the moon balanced out this centrifugal force.
Therefore in the absence of the earth's gravity moon will not fall on the earth because due to this centrifugal force moon will move along a straight line in a tangential direction at the point where gravitational force ceases to exit.
The correct statement would be that if the earth's gravity suddenly becomes zero, then the moon will not fall on the earth. Still, it will move along a straight line in a tangential direction at the point where gravitational force ceases to exit.
