Answer: Option (a) is the correct option.
Explanation:
In order to travel, sound does need a medium. The more closer the particles of a medium, the better sound can travel through it. Therefore, in solids sound travels very quickly because in solids particles are closer to each other. As a result, they can easily transmit the energy from one particle to another.
Thus, it becomes easier for sound to travel through it. On the other hand, in solids sound can travel in both longitudinal and transverse waves.
Hence, out of the given options, sound travels in transverse waves requires a medium to travel through is the correct option.
