The cloth dryer appliance works on the energy transformation from electrical energy into mechanical energy and thermal energy. Hence, option B is correct.
What is energy transformation?According to energy conservation law, energy can neither be created nor be destroyed but it can be transformed from one form to the other. Thus, energy lost by one form can be gained in other form.
In electrical devices, electrical energy is converting to various other forms. For instance, in lamps, electrical energy is converted to the light energy. Similarly in fan electrical energy is converted to the mechanical energy.
In a cloth dryer the electrical energy is converted to the mechanical energy to make it operate and this further produces the thermal energy sufficient to dry the clothes.
