Detailed Solution

The path on which she is least likely to slip is gravel.
She should walk on a gravel path because she can only walk this way. She'll have enough friction force to walk easily. The frictional force is the force created when two surfaces come into contact and slide against each other. Friction is caused by irregularities on the two surfaces that come into contact. As a result, when one object moves over another, the surface irregularities become entangled, causing friction. The more the roughness, the more irregularities and the greater the friction. So in order to reach the main road, a gravel path is more suitable as it produces more friction due to the more irregularities.
