Find the missing character?

The missing character is $\boxed{\text{K}}$.

The sequence is a list of letters that are one letter after the previous letter in the alphabet, except for the letter $\text{J}$, which is skipped. Therefore, the next letter in the sequence is $\text{K}$.

A. $\text{D}$ is incorrect because it is the third letter in the alphabet, not the fourth.
B. $\text{F}$ is incorrect because it is the sixth letter in the alphabet, not the fifth.
C. $\text{K}$ is the correct answer because it is the fifth letter in the alphabet and the next letter in the sequence.
D. $\text{P}$ is incorrect because it is the eighteenth letter in the alphabet, not the fifth.
