C. Heat is rising up the chimney.
Convection occurs when heat is transferred through the movement of fluids (liquids or gases). In the context of a fire burning in a fireplace, convection is occurring as hot air rises. The rising hot air carries heat upward, creating a flow that can be observed, for example, as the warm air moves up the chimney.
