Explanation:

Heat transfer by molecular vibration occurs through direct contact of molecules. Conduction is the process where heat is transferred through a material or between materials in contact due to molecular collisions and vibrations. Convection involves the movement of fluids (liquids or gases) carrying heat, and radiation is heat transfer via electromagnetic waves. Since the question is about molecular vibration, conduction is the relevant mode.

Answer:

Conduction
