Which of the following code snippets correctly fills in the missing code to store the size of the ArrayList in a 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: print the size of list.
        System.out.println("Size: " + size);
    }
}
