The correct answer is PushbackReader.

Here's why:

1. BufferedReader: This class reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. However, it does not have the ability to return more than one character to the input stream.

2. PushbackReader: This class adds functionality to another instance of the Reader class. It allows one to 'unread' characters, meaning it can return more than one character to the input stream. This is the correct answer.

3. BufferedWriter: This class writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. It does not have the ability to return characters to the input stream.

4. CharArrayReader: This class is used to implement a character buffer that can be used as a character-input stream. It does not have the ability to return characters to the input stream.
