Answer is Wrong!
Answer is Right!
The missing character is A.
The other three characters, G, X, and Q, are all consonants. A is the only vowel.
In the English alphabet, there are 26 letters. Of these, 5 are vowels: A, E, I, O, and U. The other 21 are consonants.
In the question, the first three characters are all consonants. The fourth character is missing. The fifth character is A, which is a vowel. Therefore, the missing character must be a vowel. The only vowel that is not already in the question is A. Therefore, the missing character is A.
