Answer 1

what do you think?

Answer 2

Energy cannot be created or destroyed. It can only be transferred from one form to another, or moved. Energy that is "wasted", like the heat energy from an electric lamp, does not disappear. Instead, it is transferred to its surroundings and spreads out so much that it becomes difficult to do anything useful with it.

Answer 3

if all of energy changed into electricity what about another form of energy(heat,light,...) so D is incorrect.
answer is C transformed to other form of energy.
