Option (a) Only the water in the pan is heated mainly by the mode of convection.

Convection is the method of heat transfer by the bulk movement of particles inside fluids like liquids and gases when heat is applied to them. the initial heat is motley provided by the conduction method but the heating of a fluid substance takes place via convection. Convection takes place due to the difference in the density of fluids.

Conduction is the process of heat transfer by direct contact due to the difference in temperature. Example utensils heat up when placed on a heater.

In the given context, the pan is heated by the virtue of conduction, and the water in the pan gets heated by the virtue of convection.
