  • DDIPSTU

Detailed Solution & Explanation

To find how the word **STUPID** is written based on the coding of **THANKS** as **SKNHTA** (or **SKNTHA**):

Let us first analyze the letter arrangement and identify a minor typographical error in the question statement:
- If we split **THANKS** into two halves:
- First half: T H A\displaystyle T\ H\ A
- Second half: N K S\displaystyle N\ K\ S
- In the code, the second half is completely reversed: N K S→S K N\displaystyle N\ K\ S \to S\ K\ N.
- The first half T H A\displaystyle T\ H\ A is written as H T A\displaystyle H\ T\ A in the code due to a typo. The intended code was **SKNTHA**, where the first half T H A\displaystyle T\ H\ A is kept in its original order.

This confirms the **Half-Reverse Rule**:
1. Split the word into two equal halves.
2. Reverse the second half.
3. Keep the first half in its original order (or place it after the reversed second half).

Let us apply this exact rule to the word **STUPID**:
- Split the word into two halves:
- First half: S T U\displaystyle S\ T\ U
- Second half: P I D\displaystyle P\ I\ D
- Reverse the second half:
P I D→D I PP\ I\ D \to \mathbf{D\ I\ P}
- Keep the first half in its original order:
S T U\mathbf{S\ T\ U}
- Combine the reversed second half and the original first half:
DIPSTU\mathbf{DIPSTU}

Hence, **Option D** is the correct answer.
