I think the answer should be 4 i.e. choice 1, since its taking 4 command parameter. Any suggestions?
yes it takes 4 parameters ...... parameter1 , parameter2 , parameter3 and parameter4
I think you should write a program that will display the args on numbered lines.
After a couple of sample runs with various arguments you should be able to easily count them
Post the code if you get stuck or have any more questions (not necessarily my suggestion, but write up something to demonstrate what the program is getting)
