Show answer & explanation
Correct answer: A
Concept
A coding-decoding rule transforms every source symbol by one consistent operation. Under a one-place backward alphabet shift, each letter is replaced by its immediate predecessor, with A wrapping to Z.
The rule must account for every aligned letter pair, not merely part of the example.
Application
Comparing KANPUR with JZMOTQ gives K→J, A→Z, N→M, P→O, U→T and R→Q; every letter moves one place backward.
Apply the same rule to MUMBAI: M→L, U→T, M→L, B→A, A→Z and I→H.
Joining the transformed letters gives LTLAZH.
Cross-check
Moving every letter of LTLAZH one place forward recovers MUMBAI, so the transformation is internally consistent.
Result
Therefore, MUMBAI is coded as LTLAZH.
