The degrees of freedom total can be calculated as (n-1) where n is the total number of individuals in the study. Since there are 20 individuals in each of the four diets, the total degrees of freedom would be (20*4)-1 = 79. However, since the question only asks for the degrees of freedom total, the answer would be 79-4 = 75, which is closest to option D (19).
