The correct answer is A. CTNLHAEI.
In the given code language, the word "BEAUTIFUL" is coded as "BFLTAEIUU." This suggests that the coding follows a specific pattern:
1. The first and last letters remain the same (B and U).
2. The second letter is the third letter of the original word (F).
3. The third letter is the fifth letter of the original word (L).
4. The fourth letter is the first letter of the original word (B).
5. The fifth letter is the second letter of the original word (E).
6. The sixth letter is the fourth letter of the original word (A).
7. The seventh letter is the sixth letter of the original word (I).
8. The eighth letter is the seventh letter of the original word (U).
Applying the same pattern to the word "TECHNICAL," we get:
T (first letter) -> C (third letter)
E (second letter) -> T (first letter)
C (third letter) -> H (eighth letter)
H (fourth letter) -> N (fourth letter)
N (fifth letter) -> I (sixth letter)
I (sixth letter) -> C (third letter)
C (seventh letter) -> A (second letter)
A (eighth letter) -> L (fifth letter)
Therefore, the coded word for "TECHNICAL" is "CTNLHAEI".
