A theory is a well-substantiated explanation relying on careful examination and testing of evidence, while a hypothesis is more tentative and is an educated guess or prediction that can be tested to support, refute or modify a theory. Therefore, a theory is more extensively tested and supported by evidence than a hypothesis. Answer A is incorrect because a hypothesis is a tentative explanation that can be refuted by new evidence, while a theory is a well-established explanation substantiated by evidence. Answer B is incorrect because a theory is based on well-established facts and evidence, and controversies may arise over interpretations or alternative theories. Answer D is incorrect because a theory has been tested more extensively than a hypothesis, which is why it is more reliable and useful for making predictions and guiding research.
