Explanation

The coding pattern consists of two distinct steps applied sequentially.
First, every letter in the source word is advanced by two positions in the alphabet (e.g., F becomes H, I becomes K).
Second, the resulting letters are rearranged: the first and second letters are swapped, the third remains in place, and the fourth and fifth letters are swapped.
Applying this to 'FIGHT': The letters become H, K, I, J, V. After swapping, the code is 'KHIVJ'.

Option A: This option, HKIJV, correctly applies the +2 positional shift to each letter but fails to perform the second step of swapping the letter pairs. It keeps the letters in their original order after the shift.
Option B: This option, WKJLI, does not follow the established +2 positional shift or the swapping pattern. The letters seem to be derived from a different, incorrect logic.
Option D: This option, URTSG, is incorrect as it uses a completely different coding scheme. For example, F is coded as U, which does not fit the +2 pattern.

Visual 1: Flowchart: A flowchart illustrating the two-step process: 1. Input Word -> 2. Apply +2 Positional Shift to each letter -> 3. Rearrange letters (Swap 1&2, Keep 3, Swap 4&5) -> 4. Final Coded Word. This visual would clarify the sequence of operations.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical reasoning, specifically coding-decoding based on alphabetical position and rearrangement as background academic context rather than a clinical decision trigger.
This question type is not directly related to clinical nursing practice.
It assesses logical and analytical reasoning skills, which are crucial for nurses in problem-solving, critical thinking, and making sound clinical judgments under pressure.
What if the pattern was a -2 shift instead of +2? For 'FIGHT', the letters would become D, G, E, F, R. After swapping, the code would be 'GDEVFR'.

How to Approach the Question

First, carefully analyze the relationship between the given word ('BELOW') and its code ('GDNYQ').
Check for simple patterns like letter reversal, direct positional shifts (+n or -n), or opposite letters (A-Z, B-Y).
Notice that B (+2) is D and E (+2) is G. The code starts with 'GD', which is a swap of the first two results. This suggests a multi-step pattern.
Verify the pattern with the rest of the word. L(+2)=N (middle position, no swap). O(+2)=Q, W(+2)=Y. The code ends in 'YQ', which is a swap of the last two results.
Confirm the rule: Shift each letter by +2, then swap the 1st and 2nd letters, and the 4th and 5th letters.
Apply this confirmed two-step rule to the target word 'FIGHT' to find the correct answer.
