Only the white and blue bulbs will operate.
Only the red and white bulbs will operate.
Which two conclusions are supported by the information shown in the diagram? Select two correct answers.
The battery in the circuit is not working.
The circuit is not complete, so the electric current is passing through the circuit.
The electric current that is passing through the circuit is producing heat.
