Answer:

B) light

Step-by-step explanation:

Light is an electromagnetic wave. Electromagnetic waves are oscillations of electric and magnetic fields that propagate in the space, carrying energy. Electromagnetic waves are NOT mechanical waves: in fact, they do not a medium to propagate, as they can also travel through a vacuum.

Electromagnetic waves are also transverse waves, which means that the oscillations of the electric and magnetic fields occur in a direction perpendicular to the direction of propagation of the wave itself.
