The correct answer is: Kinetic friction, towards east
When the person starts walking towards East, he pushes the ground in the backward direction [i.e., West].

Since friction acts in opposite direction so the frictional force will act in East direction.

Since the person is walking kinetic friction will act.
Hence option (4) is the correct answer.
