Analyze the following code:

public class A extends B {
}

class B {
public B(Strign s) {
}
}


▸ The program would compile fine if you add the following constructor into A: A(String s) { }

▸ The program would compile fine if you add the following constructor into A: A(String s) { super(s); }

▸ The program has a compilation error because A does not have a default constructor.

▸ The program has a compilation error because the default constructor of A invokes the default constructor of B, but B does not have a default constructor.
