Answer:

a. electrical energy transforming into sound energy in a speaker

Step-by-step explanation:

the law says that energy can neither be created or destroyed. answer A is an example of this because the electrical energy is turning into a different type of energy. That means the electric energy was not destroyed, it was turned into a different energy and energy was not created it just changed the type of energy.

i hope this helped!! :)
