C
G
K
T

The missing character is K.

The sequence is a list of letters that are one letter after the previous letter in the alphabet, except for the letter J, which is skipped.

A. C is the first letter in the alphabet, so the next letter in the sequence should be D.
B. G is the third letter in the alphabet, so the next letter in the sequence should be H.
C. K is the eleventh letter in the alphabet, so it is the next letter in the sequence after J.
D. T is the twentieth letter in the alphabet, so it is not the next letter in the sequence.
