public class Test1
{
public static void main (String[] args)
{
String biz = args[1];
String baz = args[2];
String rip = args[3];
System.out.println("Arg is " + rip);
}
}
run through terminal:
> javac Test1.java
> java Test1 java Myfile 1 2 2 3 4
Arg is 2.
So, option B will be right.

Command line arguments accept max index definition.....
a=args[4];
Then user must takes 4 values like java Myfile 1 2 3 4...
Another program,
a=args[3];
Then user must takes 3 values like java Myfile 2 3 4...
a=args[4];
Then user must takes 4 values like java Myfile 1 2 3 4...
Another program,
a=args[3];
Then user must takes 3 values like java Myfile 2 3 4...

The answer is right. It is all about the COMMAND LINE ARGUMENTS.
The Java application = Myfile so,
When you write a command-line arguments.
Java Myfile .....
In this case we want the output to be: Args is 2.
Java Myfile 1322.
args[0] is 1.
args[1] is 3 which is biz.
args[2] is 2 which is baz.
args[3] is 2 and since rip is args[3], the answer is C.

Why D is not correct?
It also gives output as Arg is 2.
It also gives output as Arg is 2.

It was really true when we see that program executes that the fourth location must be 2.

Agree @Suneel.
This will generate ArrayIndexOutOfBoundException.
