C Correct answer
Explanation

When Hello.txt doesn't exist, FileInputStream throws FileNotFoundException. The catch block for FileNotFoundException executes, printing 'No such file found' and returning -1. Before returning, the finally block executes, printing 'Doing finally'. The return -1 completes after finally. Therefore output is: 'No such file found' then 'Doing finally' then the method returns -1. Note: The main method prints the return value, so we see -1 after 'Doing finally'.
