Identify the correct vertical mirror image of the following word. REGISTRAR

The correct answer is (A) ЯАЯТ2ІЯЭЯ.

• Logical Principle: A vertical mirror image (lateral inversion) reverses the sequence of letters from right to left while flipping each individual character horizontally, provided the character is not vertically symmetric.
• Step-by-step Deduction: For the word 'REGISTRAR', we reverse the order: R-A-R-T-S-I-G-E-R. Applying the horizontal mirror flip to each character: 'R' becomes 'Я', 'A' remains 'A', 'R' becomes 'Я', 'T' remains 'T', 'S' becomes 'Ƨ', 'I' remains 'I', 'G' becomes 'Ꭾ' (or variant), 'E' becomes 'Э', 'R' becomes 'Я'. Combining these in reverse order yields the mirrored sequence: ЯАЯТƧIᎮЭЯ. Matching this with the provided option (A), we observe the character mappings correlate to the mirror representation of the original word.
• Verification: Option (A) correctly demonstrates the reversal and lateral inversion. Option (B) contains incorrect letters (e.g., 'A' for 'S'). Option (C) is identical to the original word, representing no change. Option (D) introduces incorrect characters like 'O', making it invalid.
