Solution

The correct option is B The earth exerts a force of attraction on the apple
$F = \frac{G m_{1} m_{2}}{r^{2}}$
According to Isaac Newton, all objects in the universe exert an attractive force on all other objects due to their masses.
The apple falls down from a tree because the earth attracts the apple with a force which is known as gravitational force.
