A)6 and 45
B)5 and 44
C)6 and 38
D)4 and 40

The degrees of freedom for the F statistic in a multiple regression analysis are calculated as the number of independent variables and the degrees of freedom for error. With 6 independent variables, the degrees of freedom for the model is 6. The error degrees of freedom is calculated as the total number of observations minus the number of independent variables minus 1 (for the intercept), which is 45 - 6 - 1 = 38.
