Correct Answer
C
Explanation
The types of waves that require a medium for propagation are called mechanical waves. Examples of mechanical waves include sound waves, water waves, and seismic waves. These waves rely on the presence of a material medium, such as air, water, or solid objects, to transfer energy from one location to another. In contrast, electromagnetic waves, such as light and radio waves, do not require a medium and can travel through a vacuum.
