A) 93
B) 81
C) 104
D) 97
🧠 Explanation:
Given: Series 1, 9, 25, 49, 121, ?
Step 1: Identify squares of odd integers → 1², 3², 5², 7², (9²), 11²
Step 2: The missing term between 49 (7²) and 121 (11²) is 9²
Step 3: Compute 9² = 81
Check: Sequence becomes 1, 9, 25, 49, 81, 121 (consistent odd squares)
Final Answer: 81
