A)The close method of the outputFile object will be automatically invoked when the try block ends, but only if no exception occurred.
B)The program will terminate with an unhandled exception if the PrintWriter constructor fails.
C)The close method of the outputFile object will be automatically invoked when the try block ends, whether or not an exception has occurred.
D)The close method of the outputFile object will be automatically invoked when the try block ends, but only if an exception occurs.

The try block in this code snippet is using a try-with-resources statement, which automatically closes the resource (in this case, the output file) when the try block ends, regardless of whether or not an exception occurred. Therefore, option C is correct. Options A and D make incorrect statements about when the close method will be invoked. Option B is incorrect because the program will not terminate with an unhandled exception if the PrintWriter constructor fails; rather, the catch block will handle the exception and print the stack trace.
