AD 17 is related to CF 13 in a certain way. In the same way, EH 29 is related to GJ 25. To which of the following is IL 38 related, following the same logic?
KN 34
XZ 34
TZ 35
TY 35
KN 34
Apply +2 to the letters for the first part and check the digit sum reduction pattern for the number: (Sum of letter positions) - 10.

Analyze Letter Transformation
Map letters to numbers (A=1, B=2,... Z=26). In AD 17 тЖТ CF 13: A+2=C, D+2=F. In EH 29 тЖТ GJ 25: E+2=G, H+2=J. Applying this to IL 38: I+2=K, L+2=N.
Analyze Number Transformation
Sum of letter values for AD: 1+4=5. Sum for CF: 3+6=9. Sum for EH: 5+8=13. Sum for GJ: 7+10=17. In AD 17, number is 17. Wait, checking internal logic: (A+D)*2 + 7 = 17? No. Correct pattern: Sum of letter values in the second pair minus the sum of letters in the first pair = constant. Actually: Sum(AD)=5, Number 17. Sum(CF)=9, Number 13. (17-13=4 difference). Sum(EH)=13, Number 29. Sum(GJ)=17, Number 25. (29-25=4 difference). For IL: Sum(I+L) = 9+12=21. Number is 38. The target number should be 38-4 = 34.
B: Letters XZ do not follow the +2 shift from IL. C: Letters TZ do not follow the +2 shift from IL and number 35 is incorrect. D: Letters TY do not follow the +2 shift from IL and number 35 is incorrect.
A is correct because the letter pair shifts by +2 and the numeric component decreases by 4 relative to the previous pair.
In analogy questions involving alphanumeric strings, always check letter shifts independently of numerical operations, as they often follow separate rules.
