Question

1. the thermonuclear fusion that occurs in the sun is a process involving ______.\

the creation of energy\
electricity and hydrogen\
heat and fused nuclei\
the destruction of energy

Explanation:

Thermonuclear fusion in the sun involves hydrogen nuclei fusing into helium nuclei, releasing large amounts of heat (and light/energy) in the process. Energy is not created (it is converted from mass per $E=mc^2$), electricity is not a direct product, and energy cannot be destroyed.

Answer:

heat and fused nuclei
