Answer is Right!
Answer is Wrong!
The missing character is $\boxed{\text{D}}$.
The sequence is a series of letters, each of which is one letter after the previous letter in the alphabet. The first letter is $\text{A}$, the second letter is $\text{B}$, the third letter is $\text{C}$, and so on. The missing letter is the fourth letter in the alphabet, which is $\text{D}$.
The other options are incorrect because they are not letters in the alphabet.
