Answer: C) Solar
Step-by-step explanation:
A non-renewable energy source is an energy source that can not be used again once it is already used. Water can be used again. For example, you can create electricity out of water, and the same water will work again to make more electricity. Geothermal heat will stay somewhere in the Earth, so it will come back and will be used again. Nuclear power can be used again when the weapon is launched, they can take the material and use it again for feature weapons. The answer has to be solar. Solar energy comes from the Sun, so it can only be used once.
