The force that causes a car to skid when taking a sharp turn is the Frictional force (Option B). Here's why:

1. When a car is moving in a straight line, the frictional force between the tires and the road surface is what allows the car to move forward without skidding. This is because the frictional force opposes the motion of the tires sliding backward.

2. When the car takes a sharp turn, the direction of the frictional force changes. It now opposes the motion of the car sliding sideways (due to the change in direction).

3. If the turn is too sharp or the speed is too high, the frictional force might not be enough to prevent the car from skidding. This is because the momentum of the car (mass times velocity) in the original direction is too great to be fully counteracted by the frictional force.

4. Therefore, the frictional force (or lack thereof) is what causes a car to skid when taking a sharp turn.

Note: While centripetal force (Option D) is involved in the process of a car making a turn (it's the force that makes the car move in a circular path), it's not the force that causes the car to skid. If anything, more centripetal force (which could be achieved by more friction or a slower speed) would help prevent a car from skidding.
