Near the end of a US cable news show, the host invited viewers to respond to a poll on the show's website that asked, "Do you support the new federal policy discussed during the show?" At the end of the show, the host reported that 28% responded "Yes," and 70% responded "No." Which of the following best explains why the results are unlikely to represent the sentiments of the population of the United States?
Difficulty: Hard
A: 

The percentages do not add up to 100%, so any possible conclusions from the poll are invalid.

B: 

Those who responded to the poll were not a random sample of the population of the United States.

C: 

There were not 50% "Yes" responses and 50% "No" responses.

D: 

The show did not allow viewers enough time to respond to the poll.
