Answer: Option (b) is the correct answer.
Explanation:
When we push the box, it will start to move as a result it will gain kinetic energy. As kinetic energy is the energy due to the motion of particles. Also there will be some friction force acting on the box.
Cohesion means the strength of holding particles together. When there is resistance in holding particles together then it is called cohesive friction.
Static friction is a force due to which an object retains at rest.
When a body is rolling on a surface then the force which resists its motion is known as rolling friction.
Thus, we can conclude that when you push a box across the floor, the box will experience a kinetic friction.
