In a certain code language, the word "KINDLE" is written as "ELDNIK" by reversing the order of its letters. Using the same coding rule, how is the word "FASHION" written in that language?

Introduction / Context:
This coding and decoding question uses a very simple but important transformation: reversing the sequence of letters in a word. The example "KINDLE" to "ELDNIK" shows exactly how the pattern works. Candidates must recognize that no shifting or substitution is involved, only reversing the order, and then apply this idea to "FASHION".

Given Data / Assumptions:

• KINDLE is written as ELDNIK in the code language.
• We are asked to find the coded form of FASHION.
• No letter replacement or arithmetic on letter positions is indicated, so the code is likely a positional reversal.

Concept / Approach:
The straightforward approach is to check whether "ELDNIK" is simply "KINDLE" written backwards. K I N D L E reversed is E L D N I K, which matches the given coded word. Once confirmed, we can apply this same reversal to FASHION. That means writing its letters from last to first, without changing the letters themselves.

Step-by-Step Solution:
Step 1: Write KINDLE and then write it in reverse order. Step 2: KINDLE has letters K, I, N, D, L and E. Reversing gives E, L, D, N, I and K, which spells ELDNIK. Step 3: This exactly matches the given code, so we confirm that the rule is "reverse the word". Step 4: Now apply the same rule to FASHION. Step 5: FASHION has letters F, A, S, H, I, O and N in order. Step 6: Reverse the order: N, O, I, H, S, A and F. Step 7: This reversed sequence spells NOIHSAF. Step 8: Therefore, the correct code for FASHION is NOIHSAF.

Verification / Alternative check:
To verify quickly, we can mentally reverse NOIHSAF and confirm that we obtain FASHION again. Reversing N O I H S A F gives F A S H I O N. This confirms that the transformation is a pure reversal and that the answer is consistent with the rule demonstrated by KINDLE and ELDNIK.

Why Other Options Are Wrong:
The other options, such as NOISHAF or NIOHSAF, contain the same letters but with incorrect internal ordering. They may come from attempts to reverse parts of the word or from letter swaps, but they do not match a complete reversal of the original sequence. Because the example clearly shows a full reversal, any option that does not preserve that exact pattern cannot be correct.

Common Pitfalls:
A common error is to reverse only a substring of the word or to accidentally change the order of two letters when writing quickly. Some candidates also try to combine reversal with letter shifting, even though the example does not require it. Focusing on the precise transformation shown in the example and carefully writing the reversed sequence helps avoid such mistakes.

Final Answer:
Since the rule is to reverse the letters of the word, the word "FASHION" is coded as NOIHSAF in the given language.
