What does verification mean in science?

Correct answer: Checking a claim using evidence or experiment

The direct answer is C: verification means checking a claim using evidence or experiment. Science does not accept a statement merely because someone says it confidently. Step by step: state the claim clearly; decide what evidence would support or challenge it; observe, measure, or perform a controlled experiment; record the results; and compare them with the claim. Repeating checks and allowing others to examine the evidence makes the conclusion more reliable. Option C is correct because it directly describes evidence-based testing. A is wrong because accepting without checking is the opposite of verification. B is wrong because changing results destroys honesty and does not verify anything. D is wrong because memorising names may help recall facts, but it is not checking a claim. Verification does not always prove an idea absolutely; it shows whether available evidence supports it and whether further testing is needed. Memory cue: verify means test before trust.
