b. reduce kinetic friction
c. increase fluid friction
d. increase kinetic friction pls you all so much : )

Answer;

B. Reduce Kinetic friction

Explanation;

-Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

-Kinetic friction is a force that acts between moving surfaces. An object that is being moved over a surface will experience a force in the opposite direction as its movement. The magnitude of the force depends on the coefficient of kinetic friction between the two kinds of material.

unbalanced force

because growing process had stoped after 4-5 year
