Answer
# Brief Explanations:
The pollster interviews students as they board buses at the end of the school - day. This is convenient for the pollster as the students are in an easily accessible location. It is not truly random because not all students have an equal chance of being selected (only those boarding buses are considered). It's not systematic (no fixed - interval selection) and not self - selected (students are not choosing to participate on their own initiative). The bias is that students who do not take the bus are not included in the sample, so the sample may not represent all students in terms of community service participation.
# Answer:
B. Convenience sampling
