Conduction is the transfer of heat through direct contact between particles. The orange option describes convection (heat transfer via fluid currents). The blue option refers to insulation. The green option is the definition of internal energy. The red option correctly defines conduction as heat transfer between particles by touch.

Answer:

Red option: Heat is transferred from one particle of matter to another by touch.
