I believe the best answer from the choices listed above is the third option. The Theory of spontaneous generation was A theory that wasdisproved by Redi and Pasteur. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Francesco Redi and Pasteur disproved the theory of spontaneous generation experimentally. The theory of spontaneous generation states that life can arise from the non living matter directly. Redi showed that if the meat was not exposed to air, flies did not develop on it. Pasteur heated the nutrients broth and showed that it was microbe free for as long as one year.
