Explanation:

Combining Groups A and C:
- Group A has 15 students and Group C has 25 students.
- When combined, Group D will have 15 + 25 = 40 students.

Finding the Average Weight of Group D:
- To find the average weight of Group D, we need the individual weights of the students in both Group A and Group C.
- Since the weights of the students are not provided, we cannot determine the average weight of Group D.

Therefore, the correct answer is option 'D' - Cannot be determined.
