Passage: There must be an external world, because if there were not something outside me that could glow or reflect light and shine light into my eyes, giving me visual experience, I would not be able to see buildings, crowds, and stars. Moreover, not only do I have such visual experience, but others also have such visual experience; the knowledge of books also repeatedly tells us that there is an external world outside us.
Question: Which of the following options does not constitute doubt or rebuttal to the above argument?
A. A.To prove the existence of the external world with sensory evidence, it is necessary to presuppose the existence of the external world in the mind.
B. B.How do you prove that others have similar visual experience to you?
C. C.Since visual experience is reliable, a mirage is not a so-called illusion, but a real existence.
D. D.If there is no external world and the knowledge of natural science is not a true reflection of it, then why does natural science achieve such great success in practice?
