D Correct answer
Explanation

The series consists of two alternating patterns. Pattern 1 (1st, 3rd, 5th...): 8, 14, 11, 14, 18 (no simple rule). Pattern 2 (2nd, 4th, 6th...): 2, 6, ?, 6, 12. Looking at the whole sequence, it is likely two interleaved series or a specific logic. However, 9 fits if the logic is +3, -2 etc., but the sequence is poorly defined.
