In a certain code language, the word "FAILURE" is written as "FRULIAG". Using the same coding rule, how is the word "SUCCESS" written in that code language?

Introduction:
This verbal reasoning question involves a non obvious code applied to words rather than a simple letter shift. We are told that the word "FAILURE" becomes "FRULIAG" under a certain transformation and are asked to determine the code for "SUCCESS" using the same rule. The question tests pattern recognition, the ability to analyze letter rearrangements, and the capacity to combine reversal and substitution ideas.

Given Data / Assumptions:
The given mapping is FAILURE → FRULIAG. We assume that the same algorithm is applied to any word to generate its coded form. The code seems to involve both rearranging letters and changing some of them, because the first and last letters in the coded word are not exactly the same as in the original. We look for a structured pattern that could be applied to "SUCCESS" mechanically.

Concept / Approach:
A helpful observation is to compare the coded word with the reversed original. If we reverse "FAILURE", we get "ERULIAF". The coded form "FRULIAG" appears to be closely related to this reversed version. Specifically, most middle letters seem to remain the same, while the first and last letters of the reversed word have been shifted to the next letter in the alphabet. Discovering and verifying this transformation allows us to apply the same steps to "SUCCESS".

Step-by-Step Solution:
Step 1: Reverse the original word "FAILURE". The reversed word is "ERULIAF".Step 2: Compare "ERULIAF" with the code "FRULIAG". We see: E becomes F, R stays R, U stays U, L stays L, I stays I, A stays A, and F becomes G.Step 3: From this, infer the rule: take the reversed word, shift the first letter of the reversed word one step forward in the alphabet, keep the middle letters unchanged, and shift the last letter of the reversed word one step forward in the alphabet as well.Step 4: Now apply this rule to the new word "SUCCESS". First reverse "SUCCESS" to get "SSECCUS".Step 5: In "SSECCUS", the first letter is S and the last letter is S. Shift both of these S letters forward by one position in the alphabet, giving T for each end position. The middle letters remain unchanged.Step 6: This produces the code "TSECCUT".Step 7: Therefore, according to the discovered pattern, "SUCCESS" is written as "TSECCUT".

Verification / Alternative check:
We can verify the logic by reapplying the same steps to "FAILURE". Reversing gives "ERULIAF". Shifting the first and last letters one step forward transforms E to F and F to G while leaving R, U, L, I, and A unchanged, giving "FRULIAG". Since this matches the given coded form exactly, the rule is confirmed.

Why Other Options Are Wrong:
The option "SSECCUS" merely reverses or preserves the original without applying the end letter shifts. "TSECCUS" shifts only the first letter and not the last one. "TSECCUU" introduces an extra U at the end which does not correspond to the systematic transformation. "SSECCUT" shifts only the last letter but not the first, again violating the discovered pattern.

Common Pitfalls:
Many learners initially search for a simple letter by letter substitution without noticing that the word is reversed first. Others may reverse the word but forget to apply the alphabetic shift to both ends or may apply the shift to all letters, which does not match the example. Looking carefully at both the order of letters and which specific letters change is crucial.

Final Answer:
The word "SUCCESS" is written as TSECCUT in the given code language.
