We don´t know for sure what can be the average for the entire class since we don´t know how many boys and girls are in the class. The equality between A and B is only true if the number of boys = girls.
1- For 2 boys and 2 girls the average is 71.
2- For 3 girls and 2 boys, the average is 69.2.
Since we cannot determine the relationthip, the answer is D.
