Which situation would result in a theory being replaced rather than revised?

A theory is generally revised when new evidence adds detail or reveals a problem that can be addressed while keeping the theory’s main ideas. If newly discovered information contradicts the existing theory so strongly that its explanation no longer works, scientists may replace it with a better one. Confirming experiments support the theory, while inconclusive results alone do not necessarily disprove it. The correct choice is B, “New information is discovered that contradicts the existing theory.”
