Answer:
Option A
Conduction
Explanation:
Heat transfer by conduction is the transfer of heat from one medium to another (mostly solids) through the vibration of the molecules about a fixed position. Materials with high thermal conductivities have high heat transfer by conduction. These materials are called conductors.
However, some materials have lower thermal conductivities and they do not conduct heat easily. These materials are called insulators. Examples include cotton or plastic. They can help prevent heat losses through conduction.
