Traditional incandescent light bulbs were used for many years and produce bright light, but the bulbs rapidly become too hot to
touch. Halogen bulbs are slightly more efficient. Compact fluorescent light bulbs (CFL) and Light-emitting diode light bulbs (LED)
generate less thermal energy. Based on this information, what types of bulbs are most likely indicated by the illustration
A)
incandescent and halogen
B)
incandescent and LED
halogen and CFL
D)
