Option b outFile. open ("outputData. out");

Explanation:

In C++, there are several classes given to handle output and input of characters to or from files. They are:

ofstream that write on files ifstream that read from files

We can use an object of ofstream to hold the contents that we wish to output to an external file. The general syntax is as follows:

ofstream_obj. open (file_name)

This will create a file with a specific file name and it possesses all the contents from the obstream_obj.
