make sure your correct because last time it was wrong

I apologize for any previous errors. However, I can confirm that the correct answer is indeed:

A) There is only a limited supply that can be used.

Nonrenewable sources of energy, such as fossil fuels (coal, oil, and natural gas), are finite and cannot be replenished within a human timescale. Once these resources are depleted, they cannot be easily replaced, making them nonrenewable.
