The second option is correct.
Convection is heat transfer by the bulk movement (circulation) of a fluid — either a liquid or a gas. Warmer, less-dense fluid rises while cooler, denser fluid sinks, creating currents that carry thermal energy. (Contrast: conduction is heat transfer by direct contact through solids or between touching materials; radiation is energy transfer by electromagnetic waves.)
