The correct response is:
**A greater percentage of the energy output of the incandescent bulb goes toward heat.**
Incandescent light bulbs convert much of the electrical energy they use into heat rather than light, making them less efficient compared to LED bulbs, which convert a higher percentage of energy into light.
**A greater percentage of the energy output of the incandescent bulb goes toward heat.**
