Solution

The correct option is D
Normal Force

Normal force is a type of contact force which acts opposite to the direction of gravity. The book kept on the table is pulled by gravity to the centre of the Earth but the table is applying a normal force opposite to it. This is the reason why the book does not go throught the table.
