Solution

The correct option is A
True

We know that sound travels the fastest in solids and the slowest in gases. So, if we put our ears on a railway track where a train is approaching from a far distance, we hear two sounds - first one is transmitted in the tracks (solid medium) and the other is transmitted through air (gaseous medium).
