A ball is thrown vertically upwards in the air. Identify the force(s) acting on it.

Correct option is B

The correct answer is gravitational force and air resistance.
Gravitational Force: The gravitational force is the force that pulls all objects towards the center of the Earth. The gravitational force is proportional to the mass of the object and the mass of the Earth. The gravitational force between the Earth and a ball is very strong, so it is the main force that causes the ball to fall back to the Earth.
Air resistance: Air resistance is the force that opposes the motion of objects through the air. Air resistance is caused by the friction between the air molecules and the surface of the object. The force of air resistance is proportional to the speed of the object and the density of the air. The force of air resistance increases as the speed of the object increases.
