Hello! Based off of the word "pseudoscience", the prefix pseudo- means fake. Pseudoscience is basically fake science. In it's real definition, it is something claimed to be scientific, but has no real evidence to back the claim up, and have sometimes been disproved in certain cases. D is out. B isn't the best answer. A doesn't really work either. The best answer and the only one that fits the definition of pseudoscience is C. The answer is C.
