When new evidence is found that contradicts part of a theory, the appropriate scientific response is generally to reevaluate the validity of the theory. Science is a dynamic process that involves testing, revising, and refining theories based on new evidence. This might lead to modifications of the existing theory, the development of new hypotheses, or in some cases, even a complete overhaul of the theory if the evidence strongly supports that. Therefore, the best option from your list is:
Science reevaluates the validity of the theory.
