Answer:

B) Only mechanical waves require a liquid, solid, or gas to travel.

Explanation:

The Electromagnetic Wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles (for example, light waves).

A mecanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium (liquid, solid, or gas) in order to transport their energy from one location to another (an example of this is water waves)
