B Correct answer
Explanation

The sequence follows an alternating pattern. Odd positions (1st, 3rd, 5th, 7th): 8, 11, 13, 15 - after the first term, increase by 2. Even positions (2nd, 4th, 6th): 12, 14, ? - continuing the pattern of adding 2 gives 16. The first term 89 seems to be an outlier or follows a different rule (8+9=17, then 1+7=8).
