What is the output of this program?

import java.util.*;
    public class Arraylist_Example 
    {
        public static void main(String args[]) 
        {
            ArrayList object = new ArrayList();
            object.add("L");
            object.add("V");
            object.add("E");
            object.add(1, "O");
            System.out.println(object);
        }
    }

1. [L, O]
2. [O]
3. [L, O, V, E]
4. [L, O, V]
5. None of these

Correct Option: C

object is an object of class ArrayList hence it is an dynamic array which can increase and decrease its size. object.add(“n”) adds to the array element n and object.add(1,”n”) adds element n at index position 1 in the list, Hence object.add(1,”O”) stores O at index position 1 of obj and shifts the previous value stored at that position by 1.
