Statistic significance requires that your sample be representative of the population, but I'm struggling with this because if the class is an elective then the answer would be: No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample of the students in her school.
BUT if the class is required, as most science classes are, then it WOULD be a random sample of the school. So the last option would be correct.

My guess though is that the teacher is looking for answer B.
