Answer
# Brief Explanations:
A reliable conclusion in statistics requires a sufficient sample size. With a school population of about 300 students, asking only 3 students (a very small sample size) is likely to lead to inaccurate results. The sample selection was random, so bias isn't the main issue. When and where she asked are less critical factors compared to the minuscule sample size.
# Answer:
A. Sample size
