A repeated-measures ANOVA typically involves comparing three or more conditions. Here, the F-ratio has 2 and 40 degrees of freedom, which suggests that there were 3 conditions because the numerator df is 2 (indicating the number of treatment conditions being compared) and the denominator df is 40 (indicating the total number of observations). Therefore, the best choice is B.
