The correct option is (C) rising steam from the cup of cocoa

Convection is defined as the flow of energy to the outer surface due to the difference in the temperature in two different parts of a liquid. The hot water rises whereas cold water sinks.

Convection is the process of heat transfer that only occurs in liquid and gases only.
