When conducting a hypothesis test regarding a population variance, the test statistic is calculated as x² from the chi-square distribution, where x is the sample variance, u is the hypothesized population variance, n is the sample size, and P0 is the level of significance. Therefore, the best choice for the test statistic is option B.
