D Correct answer
Explanation

A:B:C = 5:11:13 and B:C:D = 22:26:23 (converted from 22:25:23 by matching). For both ratios to be consistent, B must have same value. In first, B = 11k. In second, B = 22m. So 11k = 22m, giving k = 2m. A = 5k = 10m, C = 13k = 26m from first; D = 23m from second. Ratio A:B:C:D = 10:22:26:23. However, the second ratio was given as 22:25:23, not 22:26:23. These are inconsistent (C cannot be both 26m and 25m simultaneously). Therefore, the combined ratio cannot be uniquely determined. Answer D is correct.
