Answer: C
It is difficult to walk on ice because friction is low.
Walking depends on friction between the foot and the ground. The foot pushes backwards on the ground, and friction pushes the body forwards. Ice is very smooth, and a thin film of water on its surface acts as a lubricant, so the friction it can provide is small, and the foot slips instead of gripping.
High friction would make walking easier, not harder. Pressure is not the reason: the body exerts much the same pressure on ice as on any other floor.
