A medium is able to transport a wave from one location to another location because the particles of the medium are
able to interact
The explanation for the correct option:
(c) Because particles can interact with adjacent particles of the medium, it is able to transport interaction energy with them. It is due to interaction with adjacent particles that they can move.
The explanation for the incorrect options:
(a) Frictionless - this is related to the viscosity of the medium. This property is responsible for matter transportation or diffusion or fluid flow in the medium. Remember that wave motion does not transport matter, it only transports energy. Matter particles in wave motion only oscillate through their mean positions. So, this is irrelevant for wave motion.
(b) If particles would be isolated from each other, it would not be possible to transmit a wave from that medium, since it would not be able to transmit energy from it.
(d) The lightness and heaviness of particles are related to how easily waves can be transmitted through the medium, but it is not the reason for the ability of particles to transmit waves.
Hence, the correct option is C.
