Answer is Right!
The missing character is M.
The sequence is a series of letters, each of which is the next letter in the alphabet after the previous letter, except for every third letter, which is the letter M.
The first three letters are A, B, and C. The next three letters are D, E, and M. The next three letters are F, G, and H. And so on.
Therefore, the missing character is M.
