Answer 1

A

Answer 2

okay so a or b?? i need to know or suree please:))

Answer 3

my bad haha. It A because Light is a moving electromagnetic wave, and the energy it contains is carried in the moving electric and moving magnetic components of the wave. Light can move through a vacuum, and it would rather go through that than air or anything else (which scatters the energy). Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.

Answer 4
