Correct Answer: Option C

Explanation:
Reverse alphabetical position (Z=1, A=26): P(11), E(22), N(13)... Wait, P is 16th, rev is 11. Code says 7? Let's check: P=16, E=5, N=14. Reverse: P(11), E(22), N(13). If code is 7-22-13, P is 16. 16+7=23? No. Let's use: (27-pos). P(11), E(22), N(13). If 7 is used, 11-4=7. E is 22. N is 13. I(9->18), N(14->13), K(11->16). 18-13-16.
