The verified answer to “In a certain code, PLANT is written as OKZMS. How will KING be written in that code?” is JHMF, option B. The source working states: Correct answer: JHMF (Option C). Apply the same unchanged rule to KING: K→J, I→H, N→M, G→F. Therefore the required code is JHMF. Wrong options: LJOH is wrong because it does not reproduce the verified rule at every position; MKPI is wrong because it does not reproduce the verified rule at every position; IGLE is wrong because it does not reproduce the verified rule at every position. Even one mismatched position invalidates a code, so only Option C 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 JHMF. The alternatives MKPI, IGLE and LJOH fail because at least one position does not obey the same transformation. A useful final check is to map JHMF backward through the inverse operation and confirm that the original target is recovered.
