The method Files.exists() checks if a file exists at the specified path. In this case, we want to check if the file "config.txt" exists, so we need to provide the path to that file. The method Paths.get() creates a Path object for the specified path, which we can then pass as an argument to Files.exists(). Therefore, the correct expression is Files.exists(Paths.get("config.txt")).
