Show answer & explanation
Correct answer: C
Concept
In a coding-decoding problem, separate the sample word into consistent units and test transformations in a fixed order. For letter-shift rules, compare each input letter with the corresponding code letter after any rearrangement.
Once one rule explains every position in the sample without exception, apply the same sequence to the target word.
Application
Split COVALENT into two equal blocks: COVA | LENT. Reverse each block: AVOC | TNEL. Advancing every letter by one gives BWPD | UOFM, which reproduces BWPDUOFM.
Split ELEPHANT into ELEP | HANT. Reverse each block: PELE | TNAH. Advancing every letter by one gives QFMF | UOBI.
Cross-check
Moving every letter of QFMFUOBI back by one gives PELE | TNAH; reversing each block restores ELEP | HANT, and therefore ELEPHANT.
Therefore, the code is QFMFUOBI.
