I assume that you are referring to Neil deGrasse Tyson's article. I would say the correct answer is B. Scientists do not claim to have special powers. Tyson argues that the only way we can really have an insight into the world around us is not through our five senses, much less through what parapsychologists call the sixth sense. It is through scientific analysis and apparatus that science has created - through the hardware - that we get to know precisely what happens around us. Our senses even hinder our knowledge, creating false impressions about the outside world. It is true that there is so much more in the world than we can see or hear; but parapsychology is not the way to assess the truth. Science is.
As for C and D options, here's why I think they are wrong. The fact that some people profess to hear and see things others cannot is not the central thesis of this article. It doesn't explain why parapsychology is nonsense; it just defines it. And Tyson doesn't refer to any particular experiments that have shown that parapsychology is nonsense.
