B Correct answer
Explanation

When we walk, we push the ground backwards with our foot. The tendency of the foot is to move in that direction. The force of friction opposes this tendency and acts in the opposite direction. This helps us to move forward. If the force of friction between our foot and floor is small, our foot may continue to move backwards. In that case, we may slip and fall.
