Changes in the Sun's luminosity correlate exceedingly well with average land temperatures on Earth. Clearly-and contrary to accepted opinion among meteorologists-the Sun's luminosity essentially controls land temperatures on Earth.

Meteorologist: I disagree. Any professional meteorologist will tell you that in a system as complicated as that giving rise to the climate, no significant aspect can be controlled by a single variable

The reasoning in the meteorologist's counterargument questionable because that argument

(A) rejects a partial explanation, not because it is incorrect but only because it is not complete
(B) fails to distinguish phenomena that exist independently of a particular system from phenomena that exist only as part of the system.
(C) calls into question the existence of a correlation when the only real issue is that of how to interpret the correlation
(D) dismisses a hypothesis on the grounds that is fail to deal with any matters of scientific significant
(E) appeals to the authoritativeness of an opinion without evaluating the merit of a putative counterexample
