The statement that describes friction is that it is perpendicular to the surfaces that rub together.

What is a friction?

It is defined as a type of force that prevents two smooth surfaces from sliding together on each other. It is also a strong force that opposes motion when two surfaces come in contact with each other.

Some different methods to reduce friction are:

  • Application of lubricant to surfaces
  • Streamlined bodies; this goes a long way in preventing friction between two bodies.
  • Decrease in weight; reducing the amount of weight on a substance can also help to reduce friction
  • Applying wheels to objects that move/roll on the ground.

Therefore, the Option A is right.
