The Correct Option is C
Solution and Explanation
Concept:
Rearrangement of letters follows a specific position pattern.
Step 1: Analyze HILTON → IHTLNO.
Original: \[ H\ I\ L\ T\ O\ N \] Coded: \[ I\ H\ T\ L\ N\ O \] Pattern: \[ (2,\ 1,\ 4,\ 3,\ 6,\ 5) \] i.e., letters are swapped in pairs: \[ (1 \leftrightarrow 2),\ (3 \leftrightarrow 4),\ (5 \leftrightarrow 6) \]
Step 2: Apply to BILLION.
Original: \[ B\ I\ L\ L\ I\ O\ N \] Swap in pairs: \[ I\ B,\ L\ L,\ O\ I,\ N \] So result: \[ I\ B\ L\ L\ O\ I\ N \]
Hence, the coded word is IBLL0IN.
