Analyze the following code:

import java.util.*;

public class Test {
public static void main(String[] args) {
Set set1 = new HashSet();
set1.add("red");
Set set2 = set1.clone();
}
}

◦ The program will be fine if set1.clone() is replaced by (HashSet)((HashSet)set1).clone()
◦ The program will be fine if set1.clone() is replaced by (HashSet)set1.clone()
◦ The program will be fine if set1.clone() is replaced by (LinkedHashSet)((HashSet)set1).clone()
◦ The program will be fine if set1.clone() is replaced by (Set)((HashSet)set1).clone()
◦ Line 5 is wrong because the declared type for set1 is Set and the clone method is not defined Set.
