Correct answer: C
1. Identify the mathematical relationship in the given number sets. 2. Options A, B, and D follow a specific rule: First number is n, the second is n^2, and the third is n^3 - 1. 3. Option C starts with 11 and 121 (11^2), but the third number should be 11^3 - 1 = 1331 - 1 = 1330. Since the given number is 1221, it is the odd one out. Final Answer: Option C
