To find the critical value, we need to look at the degrees of freedom for the between and within groups. The degrees of freedom for the between groups is 4, and the degrees of freedom for the within groups is 40. Using an alpha level of .05 and the F-distribution table, the critical value for F with 4 and 40 degrees of freedom is 2.61. Therefore, the answer is A.
