Answer 1

The correct option is A conduction

Thermal conduction is the transfer of heat (internal energy) by rigorous vibration of the microscopic particles and transferring the energy from one particle to another without any real flow of the particles. For example, heat is conducted from the bottom of a saucepan in contact with a stove to the handle of the saucepan.
