Answer is Wrong!
Answer is Right!
The missing character is D.
The sequence is a series of letters, each of which is one letter after the previous letter in the alphabet. The first letter is A, the second letter is B, the third letter is C, and so on. The missing letter is the letter that comes after C in the alphabet, which is D.
The other options are incorrect because they are not letters that come after C in the alphabet. A is the letter that comes before C in the alphabet, B is the letter that comes two letters before C in the alphabet, L is the letter that comes four letters before C in the alphabet, and X is the letter that comes six letters before C in the alphabet.
