If a claim is falsifiable, what does that imply?

• A. It can be proven false by evidence.
• B. It can only be proven true.
• C. It is impossible to test.
• D. It is always true.

Answer: (A)

Falsifiability means there exists a possible observation or experiment that could show the claim is false. In science, this allows ideas to be tested and potentially rejected when evidence disagrees. So a falsifiable claim can be disproven by evidence—one contradicting observation is enough to refute it. It isn’t about being provable true, and it isn’t about being impossible to test or always true; those would not align with the idea that there must be a possible test that could show the claim false.
