Consider the following code snippet: How can the program ensure that the file will be closed if an exception occurs on the writeData call?
A)The program should place the outputFile.close() statement within a try block to ensure that the file will be closed.
B)The program should declare the PrintWriter variable in a try-with-resources statement to ensure that the file is closed.
C)It is not possible to ensure that the file will be closed when the exception occurs.
D)The program does not need to take any action, because the output file will be automatically closed when the exception occurs.

The best choice is to declare the PrintWriter variable in a try-with-resources statement. This will automatically close the file when an exception is thrown, ensuring that the file is properly closed regardless of any errors that occur. Placing the outputFile.close() statement within a try block (option A) can work, but it is not as safe as using a try-with-resources statement because it is possible for the programmer to forget to put the close statement in the correct location. Option D is incorrect because the output file will not be automatically closed when an exception occurs. Option C is also incorrect because it is possible to ensure that the file will be closed.
