Solution
The correct option is A free convection+conduction
Water inside the pipe is heated by conduction by direct contact of pipe to the container having higher temperature.When the pipe is heated on fire the water neat the bottom surface of pipe becomes hotter i.e. at higher temperature and becomes less dense and hence move up and the colder water which is more dense comes down and convection current sets up. So; water inside the pipe can heated by conduction and free convection.
