what is the answer

The energy conversion when a solar cell is used to light a street lamp is Option B: solar energy - electric energy - light and heat energy

Explanation:

From the 'Law of conservation' of energy, energy cannot be 'created' nor it can be destroyed. But we can convert energy from 'one form' to 'other'. The devices that transform energy from one form to another are called transducers.  

'Solar cells' also known as  the photo voltaic cells. These devices transform light energy into electrical energy directly. When these solar cells are used in a street lamp, it will convert this electrical energy into heat and light energy.
