Which statement defines a scientific law?

• A. An opinion
• B. An explanation of events that always leads to the same outcome
• C. A fact that cannot be tested
• D. A model

Answer: (B)

A scientific law is a concise statement that describes a consistent pattern or relationship observed in nature under specific conditions, often expressible with a mathematical form, and it helps predict what will happen under those conditions. That’s why the statement describing events that always lead to the same outcome fits best. It captures the idea that, under the same conditions, nature behaves in a repeatable, predictable way—the essence of a law. It isn’t an opinion, since laws are grounded in observations and tested repeatedly. It isn’t a fact that cannot be tested, because scientific claims are open to testing and revision with new evidence. And it isn’t a model, which is a simplified representation used to explain or visualize phenomena rather than a rule describing the pattern itself.
