Answer:

C. Conduction

Explanation:

The transfer of heat in solid materials is primarily through conduction, which involves the transfer of heat between two objects that are in direct contact with each other. This means that the heat is transferred from a region of higher temperature to a region of lower temperature by the collisions between particles.

Option C, conduction, is the correct answer in this case. Convection involves the transfer of heat by the movement of fluids, and radiation involves the transfer of heat through electromagnetic waves. An insulator, on the other hand, is a material that resists the flow of heat and does not allow it to pass through easily.
