Show answer & explanation
Correct answer: C
Solution: Determine the encoding rule and apply it to BOMBAY.
Rule: For the nth letter in the word, shift that letter backward by n positions in the alphabet (A=1, B=2, ... Z=26). If the result is less than 1, add 26 to wrap around.
Verify rule with examples: DELHI -> D(4)-1=C, E(5)-2=C, L(12)-3=I, H(8)-4=D, I(9)-5=D → CCIDD. SIGHT -> S(19)-1=R, I(9)-2=G, G(7)-3=D, H(8)-4=D, T(20)-5=O → RGDDO.
Apply to BOMBAY letter by letter:
B -> A (2 - 1 = 1 → A)
O -> M (15 - 2 = 13 → M)
M -> J (13 - 3 = 10 → J)
B -> X (2 - 4 = -2 → -2 + 26 = 24 → X)
A -> V (1 - 5 = -4 → -4 + 26 = 22 → V)
Y -> S (25 - 6 = 19 → S)
Final coded word: AMJXVS
