Answer : Option A) Increases.
Explanation : Pressing two objects together with more force will increase the friction.
Friction is defined as the resistance to motion of an object which is relative to another.
If the forces acting between the two objects are found to be vertical then they will have an effect of increased friction as they increase the weight.
When forces are assumed to be horizontal then, the result of weight gets multiplied by the coefficient of friction which will result in having no effect on the friction.
