Number of students in group D is more then number of students in group A or group C. But there is no information about the weight of students in group A or group C. Hence answer is D.

Answer is B. Since average depends upon number of children. As number of children in Group D are more so average will be more. • Like

Since we do not know the average weight of the class or average weight of each group, we cannot determine average weight of the students in group-D

Hence option D is the correct answer
