Detailed Solution

The speed of sound in a medium is given by:

Solids have a much higher bulk modulus $B$ compared to gases, which makes the sound travel faster in solids.

False – The reason states that gases have a higher bulk modulus than solids, which is incorrect.

In reality, solids have a much higher bulk modulus than gases, which is why the speed of sound is greater in solids.
Gases have the lowest bulk modulus, making the sound travel slowest in gases.

A is true, but R is false.
