32 kg

- Given the average weight of A, B, C, and D is 33 kg, the total weight is 132 kg (4 x 33 kg).

- C is 12 kg lighter than A, so if A = x, then C = x - 12.

- B is 6 kg heavier than C: B = (x - 12) + 6 = x - 6.

- D is 10 kg lighter than C: D = (x - 12) - 10 = x - 22.

- Thus, the weight equation is: x + (x - 6) + (x - 12) + (x - 22) = 132.

- Solving, 4x - 40 = 132, gives 4x = 172, so x = 43.

- Average weight of A and D: (A + D)/2 = (43 + 21)/2 = 32 kg.

- Option 4, 32 kg, is the correct answer.
