CDBefore opening a file for reading or writing, it's a good practice to check if the file exists to avoid runtime errors. Therefore, option B is correct as it checks for the existence of the file. Options C and D are also correct as they demonstrate how to open a file for reading, but the choice between "pictureFrame57.txt" and "pictureFrame.txt" depends on the actual file name intended for use.
