Explanation:

1. A hypothesis is a proposed explanation, not a statement of a consistent natural phenomenon.
2. A scientific theory is an explanation of a natural phenomenon, while a scientific law describes a consistent natural phenomenon (like the conservation of energy here, which states how energy behaves in nature).
3. The statement about energy (cannot be created/destroyed, only changes form) is a scientific law as it describes a consistent, observable natural phenomenon.

scientific law
