Correct answer: C
Concept
In a position-based letter code, first map each letter to its alphabet position from 1 to 26. Apply the position-specific shift to each letter independently, wrapping around the alphabet whenever subtraction goes below 1.
Application
From DELHI to CCIDD, the first through fifth letters move backward by 1, 2, 3, 4, and 5 places respectively: D→C, E→C, L→I, H→D, I→D.
Continue the same position rule for the six letters of BOMBAY, so the backward shifts are 1, 2, 3, 4, 5, and 6.
Apply the shifts in order: B−1=A, O−2=M, M−3=J, B−4=X after alphabet wraparound, A−5=V after wraparound, and Y−6=S.
Cross-check
The resulting letters A, M, J, X, V, S use exactly the same increasing backward-shift pattern as the example, including the required alphabet wraparound for B and A.
Result
Therefore, BOMBAY is coded as AMJXVS.
