Answer is Wrong!
Answer is Right!
The missing character is C.
The sequence is a simple alternating repetition of the letters A and B. The first letter is A, the second letter is B, the third letter is A, and so on. The missing letter is the third letter in the sequence, which is C.
The other options are incorrect because they are not in the sequence. Option A is C, which is the fourth letter in the sequence. Option B is B, which is the second letter in the sequence. Option C is H, which is not in the sequence. Option D is I, which is not in the sequence.
