For a hypothesis to be used in science, it must be testable and falsifiable. This means that the hypothesis can be subjected to experiments or observations that could potentially prove it wrong. Among the options you provided, none explicitly state "testable and falsifiable," which is the key requirement for a scientific hypothesis. However, if we had to choose from the listed options, we would focus on the idea that a valid hypothesis should allow for tests that can validate or invalidate it, which aligns with option C: it must be reproducible.
Therefore, the best answer is it is testable and falsifiable, although this specific wording does not appear in your options.
