"It is driven by temperature differences within a fluid."
Convection is heat transfer by bulk motion of a fluid (liquid or gas) caused by temperature (and resulting density) differences—warm fluid rises and cooler fluid sinks. The other options describe conduction (particle collisions), incorrectly include solids, or state the cooling/rising process backwards.
