Question

Quizplus · Accepted Answer

The correct answer is C because when the horse suddenly starts running, the lower part of the rider's body moves forward with the horse due to being in contact with it, while the upper part of the body tends to remain at rest due to inertia of rest. This discrepancy in motion between the upper and lower parts of the body can cause the rider to fall.
