Prethinking : The executive clearly provides numbers that are against the pundits claim, but executive's numbers represent only a small pool of the total TV viewership. Pundits were talking about the total TV viewership but the executives numbers are only for TV networks A, B, C and D. There can be many more TV networks.
A. Attacks the character of the pundits rather than addressing their arguments
The executives clearly attacks the numbers provided by the pundits by mentioning his own numbers. The executive didn't attack the charecter of the pundits.
INCORRECTB. Fails to demonstrate that the pundits mentioned are not experts in the area of television viewership
The executive didn't talk about the credibility of the pundits mentioned.
INCORRECTC. Incorrectly concludes that something is not true based on the claim that it has not been demonstrated to be true
This option is partially true. Even though the executive concludes that the pundits were wrong in their claim, the reason used by the executive is different from the reason specified in this option C.
INCORRECTD. Draws evidence from only a small pool of available sources, which may be nonrepresentative
This option matches the prethinking. The executive based his argument on only four networks which mights represent only a small pool of total TV networks.
E. Relies upon an emotional appeal in an effort to persuade the listener
This option is not vulnerable to criticism as the executive presented the true numbers of the TV networks.
Hence option D
