When heat is transferred from one particle of hot body to another by actual motion of the heated particles, it is referred to as heat transfer by:

The correct option is A Conduction
Each solid contains atoms in a regular arrangement having the attractive forces amongst them. They vibrate about their mean positions without leaving their place. On heating one of the solid, its atoms at the heated end absorb energy and begin to vibrate with the large amplitude. They set the neighbouring atoms also in vibration by the transfer of a part of the energy to them. These atoms on gaining heat energy now begin to vibrate with the large amplitude and set the other neighbouring atoms in vibration by transferring a part of the energy to them. This process continues till the atoms at cold end begin to vibrate with increased amplitude. In this process, the atoms of medium do not leave their positions, but they transfer heat energy through their vibrations.
