Answer
# Brief Explanations:
1. **A**: Since Patrick asks only his website - visiting listeners to participate, it's a non - random sample, so this is a valid bias reason.
2. **B**: The size of the sample (200 respondents) is not the reason for bias. Bias is related to how the sample is selected, not the number of respondents.
3. **C**: There may be non - response bias as only those who visit the website and choose to respond are included, leaving out those who don't visit or don't respond, so this is a valid bias reason.
4. **D**: The people who visit the website and respond are more likely to be fans of the show, which causes bias, so this is a valid bias reason.
# Answer:
B. The results are biased because the sample includes only 200 respondents.
