Verified by Experts
The correct answer is:
B

Conduction is the process of transmission of heat in a body from the hotter part to the

colder part without any bodily movement of constituent atoms or molecules of the body.

In convection, the heated lighter particles move upward and colder heavier particles move downward

to their place. This depends on weight and hence, on gravity.

Radiation is the process of transmission of heat from one body to another body through

electromagnetic wave even through vacuum, irrespective of their temperatures.
