A

Step 1: Understand the forces acting on an object during pushing and pulling.
When a body is pushed, the force is applied horizontally which increases the normal force acting on the body, thereby increasing the frictional force that opposes the motion. In contrast, when pulling, the force can be applied at an angle which may reduce the normal force and hence the frictional force.
Step 2: Analyze the coefficient of friction. The coefficient of friction is a measure of how much frictional force is present between two surfaces. It can be different for pushing and pulling because of the angle of force application.
Step 3: Conclusion: Since it is easier to pull a body than to push it primarily because the coefficient of friction is generally lower when pulling than when pushing.
Therefore, the correct answer is Option A: the coefficient of friction is more in pushing than that in pulling.
