Solution

The correct options are
B light energy
C heat energy
If you've ever touched a bulb that has been glowing for a while, you will realise that glass is hot. This is because, when a bulb is switched on, most of the electrical energy gets used in transmitting light, but some of that energy is also dissipated in the form of heat.
