Conduction is defined as the process in which there is transfer of heat through the material of substance due to the difference in temperature of adjoining regions.
For example, cooking omelet in a pan is a conduction process.
Thus, we can conclude that out of the given options conduction is the process which describes the transfer of heat through matter by molecular activity.
