The verified answer to “In a certain code, QUEEN is written as JFVVM. How will FOOD be written in that code?” is ULLW, option B. The source working states: Correct answer: ULLW (Option C). Apply the same unchanged rule to FOOD: F→U, O→L, O→L, D→W. Therefore the required code is ULLW. Wrong options: GPPE is wrong because it does not reproduce the verified rule at every position; HQQF is wrong because it does not reproduce the verified rule at every position; ENNC 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 ULLW. The alternatives HQQF, ENNC and GPPE fail because at least one position does not obey the same transformation. A useful final check is to map ULLW backward through the inverse operation and confirm that the original target is recovered.
