C Correct answer
Explanation

The sequence is 4, 6, 9, 10, 12, 14. The pattern of differences is +2, +3, +1, +2, +2. If the sequence were 4, 6, 8, 10, 12, 14, it would be an arithmetic progression with difference 2. Thus, 9 is the wrong term.

AI explanation

The series follows a pattern of alternating composite and prime numbers. The numbers 4, 6, 10, 12, and 14 are all even composite numbers, while the number 9 is an odd composite number. The number 9 breaks the alternating sequence because it should be a prime number like 7 or 11. The result is 9.
