Maritza Fernandez · Answer 1

It should be b because physical laws of conservation of energy and matter dictate that the energy is still emitted in some form, so a and d are incorrect. Energy does not convert into matter when it comes light bulbs, therefore b is also incorrect. That leaves only b which is the correct answer.

The rest of the energy that is not transformed into light becomes thermal energy
