Answer is Wrong!
Answer is Right!
The correct answer is A. A single character.
The question mark (?) is a wildcard character that can be used to represent any single character in a file name.
For example, if you are searching for a file named “file1.txt” and you use the question mark as a wildcard, you will also find files named “file2.txt”, “file3.txt”, and so on.The other options are incorrect. Option B is incorrect because the question mark can only represent a single character, not a group of characters. Option C is incorrect because the question mark is not used to represent questions. Option D is incorrect because the question mark is a valid character that can be used in file searching.
