A. It increases the flow of electric current by acting as a conductor as it converts electrical energy to light and heat.

B. It resists the flow of electric current, converting electrical energy into light and heat.

C. It decreases the flow of electric current by acting as an insulator as it converts electrical energy to light and heat.

D. It converts electrical energy into light and heat while maintaining an uninterrupted flow of electric current.
