In a certain code language THUNDER is written as UHTNRED by rearranging its letters. Using the same pattern of rearrangement, how will the word THIEVES be written in that code?

Introduction / Context:
This is another letter rearrangement analogy. The word THUNDER is jumbled into UHTNRED according to a fixed order of positions. To encode THIEVES, you must first decode the exact positional pattern used for THUNDER and then apply that same pattern to the letters of THIEVES.

Given Data / Assumptions:

• Original word: THUNDER
• Coded word: UHTNRED
• Target word: THIEVES
• Code uses only rearrangement, no insertion or deletion of letters.

Concept / Approach:
As with similar rearrangement codes, the main technique is to index each letter in the original word and then see from which index each letter of the code word comes. That index mapping is then used as a template for any other word of the same length. Since both THUNDER and THIEVES have seven letters, the same seven position pattern can be reused.

Step-by-Step Solution:

Verification / Alternative check:
Check that all letters of THIEVES appear exactly once in IHTESEV. Both contain T, H, I, two Es, V, and S. None of the letters are lost and none are duplicated beyond what appears in the original word. Also confirm the mapping on THUNDER again to ensure the positional pattern was not misread.

Why Other Options Are Wrong:

• ITHESEV uses most letters but does not follow the 3, 2, 1, 4, 7, 6, 5 order of positions.
• IHTEESV shifts the second E into a different position than the pattern demands.
• IHTSEVE changes the relative ordering of S, E, and V and breaks the exact positional mapping.
• IHEESTV is simply a different scramble without any link to the specific pattern found from THUNDER.

Common Pitfalls:
Learners sometimes try to spot a visual pattern only and choose the option that looks closest to the original word. In coded rearrangement questions, however, small differences in order can completely change the correctness. Always decode the exact positional mapping first and then apply it systematically.

Final Answer:
The correct coded form of THIEVES is IHTESEV.
