Show answer & explanation
Correct answer: B
Decoding rule: Each number n corresponds to the letter whose position in the alphabet is 27 − n (for example, 26 → A, 25 → B, 24 → C).
Apply this rule to each option:
11 - 26 - 16 - 13 decodes to 11 → P, 26 → A, 16 → K, 13 → N → "PAKN" (not a country).
13 - 22 - 11 - 26 - 15 decodes to 13 → N, 22 → E, 11 → P, 26 → A, 15 → L → "NEPAL" (a country).
16 - 26 - 11 - 14 - 26 decodes to 16 → K, 26 → A, 11 → P, 14 → M, 26 → A → "KAPMA" (not a country).
18 - 19 - 22 - 12 - 18 - 26 decodes to 18 → I, 19 → H, 22 → E, 12 → O, 18 → I, 26 → A → "IHEOIA" (not a country).
Answer: 13 - 22 - 11 - 26 - 15 decodes to NEPAL, so this sequence represents the name of a country.
