Final answer:
Karl Popper's philosophy differentiates science from pseudoscience by emphasizing falsification, the ability of a hypothesis to be tested and possibly be shown false through empirical evidence and replication of results. the correct option is A.
Step-by-step explanation:
According to Karl Popper, science (unlike pseudoscience) is based on falsification, testing hypotheses in ways that allow them to be refuted. Karl Popper's philosophy of science emphasizes the ability to refute hypotheses through testing. This approach distinguishes scientific inquiry from pseudoscience, which tends to seek confirmation rather than potential disproof.
The scientific method is an iterative cycle, starting with observation, followed by hypothesis formation, experimentation, and conclusion. If experiments do not support the hypothesis, it is revised or discarded, and new hypotheses are formed. This is fundamental to scientific progress as it allows the scientific community to build upon evidence-based theories, refining or rejecting them based on empirical data.
