Without the specific output data, we can infer that if a conclusion about the population means is mentioned as not unreasonable, it suggests that statistical analysis (e.g., a hypothesis test or confidence interval) did not provide strong evidence against the null hypothesis that the difference in population means is 0. This does not directly inform us about the sample means or their positivity, hence only option B is correct based on the given choices.
