Explanation:

Voluntary response samples are often biased as those with stronger opinions are more likely to respond. Just because the number of responses (354) is above the required 200 does not mean it is a good - quality sample. A random sample is generally more representative, but this is a voluntary response sample (people chose whether to respond or not).

Answer:

B. No, because it is a voluntary response sample.
