Solution
The correct option is B Convection
Convection is the process of heat transfer by the motion of a fluid (such as water). In the above case, we observe that convection currents are being set up in case of boiling. Here water is in contact with the hot base and it gains heat from the hot base through conduction. As hot water is less dense than cold water, it rises up pushing the cold water below, which in turn gets heated.
