Hint:Before we start addressing the problem, we need to know about centrifugal force. Centrifugal force is defined as the apparent outward force that acts on a mass when it is rotated. When an object or a particle is moving in a circular motion, then the force which acts away from the center is known as centrifugal force.
Complete step by step solution:
Whenever a body passes through the curve centripetal force acts on the body and the direction of the force is at the body and is always acting towards the center of the curve. The centripetal force is necessary to act on the body as the curve arises to balance the forces on the body.
But in the same situation, the outward force also acts on the body known as the centrifugal force. The formula of centrifugal force is,
\[F = m{\omega ^2}r\]
Where, m is mass of the body, \[\omega \] is angular velocity and r is radius.
The centrifugal force is a pseudo force that acts away from the center and it arises due to the inertia of a body. Therefore, when a car is moving with high velocity when it has to turn, a force that acts in outward direction is because of the centrifugal force.
Hence, option B is the correct answer.
Note: In this problem it is important to remember that whenever an object or a particle is moving in a circular motion a pseudo force comes into existence known as centrifugal force and this force acts away from the center whereas the centripetal force acts towards the center.
