Answer :
Walking on a wet floor is difficult because there is less friction between your feet and the ground. Hence the correct option is b.
Walking on a wet floor is difficult primarily due to the decrease in friction between your feet and the ground. When a surface is wet, a thin layer of water creates a barrier between the soles of your shoes and the floor, reducing the friction that provides traction during walking. Friction is the force that opposes relative motion between two surfaces in contact, and it is crucial for maintaining stability and preventing slipping.
In the case of a wet floor, the presence of water diminishes the ability of your shoes to grip the surface, making it more challenging to walk securely. This reduction in friction is why walking on a wet floor feels slippery and requires extra caution to prevent accidents. Hence the correct option is b.
