Explanation:

Friction is a force that opposes the relative motion or tendency of relative motion between two surfaces in contact. Static friction acts when there is no relative motion between the surfaces (e.g., a book at rest on a table). Kinetic friction (also known as dynamic friction) acts when there is relative motion between the surfaces (e.g., sliding a book on a table). Elastic friction is not a standard type of friction in physics.

Answer:

B. dynamic friction, C. kinetic friction, D. static friction
