B Correct answer
Explanation

The sequence follows two interleaved patterns: first digits are 1,3,5,7,9 (increasing by 2) and second digits are 3,5,7,9,1 (decreasing by 2, with wrap-around). After 911, the next would be 1113 (first digit 11, second digit wraps from 1 to 3). Option B (1113) is correct. This is a complex dual-pattern sequence.
