Hi TPWK,

C tells us that a theory is likely right if it accounts for something that is not adequately accounted for by another theory. If this were true, this would maybe support the view of the scientists the professor argues against. However, it is not something that the professor must believe is true.

The author must believe E. If it is true that relativity includes a light absorbing mechanism, the argument makes no sense.
