Which of the following statements opens a file named temp.dat for output?

The correct answer is A. outFile.open(“temp .dat”);

The other options are incorrect because they do not use the correct syntax to open a file for output.

Option B, fileOut.output(“temp .dat”), does not use the correct keyword to open a file. The correct keyword is “open”, not “output”.

Option C, openFile.out(“temp .dat”), does not use the correct syntax to open a file. The correct syntax is “openFile.open(“temp .dat”)”, not “openFile.out(“temp .dat”)”.

Option D, fileOpen.out(“temp .dat”), does not use the correct syntax to open a file. The correct syntax is “fileOpen.open(“temp .dat”)”, not “fileOpen.out(“temp .dat”)”.

Option E, out.fileOpen(“temp .dat”), does not use the correct syntax to open a file. The correct syntax is “outFile.open(“temp .dat”)”, not “out.fileOpen(“temp .dat”)”.
