Answer 1

The correct statement about a hypothesis is that it must be validated by scientific experiments to be supported as a potential theory.

Step-by-step explanation:

The correct statement about the hypothesis is: a. The hypothesis must be validated by scientific experiments. This means that a hypothesis is a proposed explanation for a phenomenon that needs to be tested through experimentation. While hypotheses should be concise and relate to physical quantities, they don't have to apply to all situations in the universe, nor are they always short statements. Validating a hypothesis through scientific experiments is crucial to converting it into a theory.
