Correct answer: D
Solution:
Use the two given codes to deduce the digit-to-letter mapping.
From 15789 = AXBTC we get: 1 → A, 5 → X, 7 → B, 8 → T, 9 → C.
From 2346 = MPDU we get: 2 → M, 3 → P, 4 → D, 6 → U.
Now encode 23549 by replacing each digit with its mapped letter: 2 → M, 3 → P, 5 → X, 4 → D, 9 → C, giving
MPXDC
Answer: MPXDC
