Which of the following best describes a mathematical wave

A: A transfer of energy

B: A movement of matter

C: When energy is converted from one form to another

D: A periodic disturbance of a medium

Answer: D:

A periodic disturbance of a medium

Explanation:

A wave can be Mathematically defined by periodic disturbance of a medium. That is, oscillations of the waves about a fixed position or change in position from the resting equilibrium position. The wave oscillate from equilibrium position with amplitude periodically.
