(C) is the correct option.
Thermal conduction happens when atoms excited by the heat of the nearby atoms get heated themselves leading to the heating of the entire body:
- The highest rate of conduction can be observed in solids because the particles are located extremely close to each other leading to immediate heat transfer.
- The most common example of conduction is the transfer of heat from the stove to the pan. The part of the pan heats first gradually leading to the heating of the entire pan.
