In a one-way ANOVA, there are c groups (or treatments) and n total observations. The degrees of freedom for the numerator of the F test is the number of groups minus 1, which is c - 1. The degrees of freedom for the denominator is the total number of observations minus the number of groups, which is n - c. Therefore, the degrees of freedom for the F test are (c - 1) and (n - c). Hence, option A is the correct choice.
