Correct Answer

✅ Option b — ETUPMOCR

All Options:

  • APMOCRETU
  • BETUPMOCR
  • CUTEPMOOR
  • DMOCPETUR

Detailed Solution & Explanation

Let's analyze the coding pattern of the word **INACTIVE**:
1. The word has 8\displaystyle 8 letters: I-N-A-C-T-I-V-E\displaystyle \text{I-N-A-C-T-I-V-E}.
2. The coding reverses the first 7\displaystyle 7 letters (I-N-A-C-T-I-V→V-I-T-C-A-N-I\displaystyle \text{I-N-A-C-T-I-V} \to \text{V-I-T-C-A-N-I}) and leaves the last letter (E\displaystyle \text{E}) unchanged.
3. Reversing the first 7\displaystyle 7 letters and keeping E\displaystyle \text{E} yields V-I-T-C-A-N-I-E\displaystyle \text{V-I-T-C-A-N-I-E} (printed as 'VTCANIE' with a slight typo in the question where the second 'I' was omitted).

Now, let's apply the exact same coding logic to the word **COMPUTER**:
1. The word has 8\displaystyle 8 letters: C-O-M-P-U-T-E-R\displaystyle \text{C-O-M-P-U-T-E-R}.
2. Extract and reverse the first 7\displaystyle 7 letters (C-O-M-P-U-T-E\displaystyle \text{C-O-M-P-U-T-E}):
C-O-M-P-U-T-E→ReverseE-T-U-P-M-O-C\text{C-O-M-P-U-T-E} \xrightarrow{\text{Reverse}} \text{E-T-U-P-M-O-C}
3. Keep the last letter (R\displaystyle \text{R}) at its original position and append it:
Result=ETUPMOCR\text{Result} = \text{ETUPMOCR}

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