Critical Reasoning

The growing popularity of computer-based activities was widely predicted to result in a corresonding decline in television viewing. Recent studies have found that, in the United States, people who own computers watch, on average, significantly less television than people who do not own computers. In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since_______.

(A) many people who watch little or no television do not own a computer.
(B) even though most computer owners in the United States watch significantly less television than the national average, some computer owners watch far more television than the national average.
(C) computer owners in the United States predominately belong to a demographic group that have long been known to spend less time watching television than the population as a whole does.
(D) many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television.
(E) many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television.

I have a doubt with A. I think that can be correct too. Let me explain, the author assumes that people watch television. If he doesn't make that assumption, he couldn't claim that people have not reduced the time dedicated to watch TV.

But, what happened if the respondents in the survey reported that they don't watch television. The author couldn´t claim that the time for computers activities has not replaced the time to watch TV because simply there is not replacement. There is not a competition between the time to watch TV and use computers.
