Consider the following code segment. Which statement, when used to replace // Missing Code, will correctly store the number of elements in the ArrayList in the size variable?

import java.util.ArrayList;
public class Test {
    public static void main(String[] args) {
        ArrayList<String> list = new ArrayList<String>();
        list.add("Alpha");
        list.add("Beta");
        // Missing Code
        System.out.println("Size: " + size);
    }
}
