If in a certain code language “SURFER” is coded as “RUSREF”, how would…

Concept: In this letter-coding pattern, a word is split into two equal halves, and each half is reversed on its own — not the whole word as one block. The two reversed halves are then written down in the same left-to-right order as the original halves.

As given: SURFER (6 letters) splits into SUR and FER. Reversing each half gives RUS and REF, so the two reversed halves written in order form RUSREF — matching the coded word in the question.

1. KNIGHT has 6 letters, so it splits into two equal halves: KNI and GHT.

2. Reverse the first half: KNI becomes INK.

3. Reverse the second half: GHT becomes THG.

4. Write the two reversed halves in the same order as the original halves: INK followed by THG, giving INKTHG.

Cross-check: reversing the entire word as a single block (KNIGHT -> THGINK) does not match any offered code, and applying the same rule back to RUSREF (REF becomes FER, RUS becomes SUR, restoring SURFER) confirms the rule works consistently in both directions — the code for KNIGHT is INKTHG.
