The F-test in ANOVA is used to compare the variability of the means between groups to the variability within groups. The test statistic F is the ratio of the mean squared error (MSE) to the mean squared treatment (MSTR), which is equivalent to the ratio of the between-group variance (SSTR) to the within-group variance (SSE). Therefore, the correct choice is B, which represents the ratio MSTR/MSE.
