The verified answer to “In a certain code, GARDEN is written as NGARDE. How will NOTE be written in that code?” is ENOT, option C. The source working states: Correct answer: ENOT (Option D). Apply the same unchanged rule to NOTE: N→E, O→N, T→O, E→T. Therefore the required code is ENOT. Wrong options: OPUF is wrong because it does not reproduce the verified rule at every position; PQVG is wrong because it does not reproduce the verified rule at every position; MNSD is wrong because it does not reproduce the verified rule at every position. Even one mismatched position invalidates a code, so only Option D is correct. This observation must be confirmed across every available letter position or every consecutive term before it is applied to the missing code. Applying the verified rule to the target expression produces ENOT. The alternatives PQVG, MNSD and OPUF fail because at least one position does not obey the same transformation. A useful final check is to map ENOT backward through the inverse operation and confirm that the original target is recovered.
