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