- ATSR
- BVUT
- CSTU
- DUTS
Step-by-Step Solution
Each letter is replaced by its mirror counted from the far end, so the positions of a pair always add to 27. B (2) becomes Y (25), C (3) becomes X (24) and D (4) becomes W (23). Applying the mirror to F (6), G (7) and H (8) gives U (21), T (20) and S (19), that is UTS. 'TSR' and 'VUT' are each one shift off the mirror, and 'STU' reverses the correct letters.
Answer: D) UTS
