Is my answer correct?

question

Scott was watching the electrician install a new light fixture. Scott noticed that when he was finished, he carefully wrapped some wires with plastic caps and black plastic tape. Select the best explanation of why the electrician would wrap electrical wires with plastic products.


answer I chose

The electrical wires are made of metal, which conducts electricity. In order to make the wiring safe, he would wrap the exposed wire with plastic materials, which are good insulators. This keeps the flow of electricity contained to the light fixture and wiring.
