Final Answer :
A
Explanation :
The degrees of freedom indicated by dfBG represents the number of levels of the independent variable. Therefore, the best choice is A. The other options are incorrect as dfWG represents within-group variability, the size of the sample cannot be determined by the degrees of freedom, and the directionality of the alternative hypothesis has no bearing on the degrees of freedom.
