The idea of electronic books, or e-books, has an indisputable allure. In reality, however, e-book technology is still too immature to be practical for most people. With only a few thousand titles available as of 2001, those who want to read electronically have very little to choose from. According to PC Magazine, "the likelihood of people reading novels or even magazines digitally in the future is low."

What undermines the credibility of this argument?
A. The author supports the argument with a figure that is outdated.
B. The author demonstrates a clear bias against electronic books.
C. The author cites a magazine that does not appear to be credible.

A. The author supports the argument with a figure that is outdated.

The correct answer is A. The author supports the argument with a figure that is outdated. This undermines the credibility of the argument because using a statistic from 2001 is not relevant or accurate in assessing the current state of e-books.
