• Incorrect. While some theories may start as speculative, a good theory is grounded in evidence and can be tested and validated through research and experimentation.

C. Presents facts that support the theory and disregards evidence that contradicts it.

• Incorrect. A good theory should be open to scrutiny and consider all evidence, including that which may contradict it. Ignoring contradictory evidence is a sign of bias and weakens the credibility of the theory.
