AP Computer Science A· difficulty 4/5

public class A {
    public String name() { return "A"; }
}
public class B extends A {
    public String name() { return "B-" + super.name(); }
}
public class C extends B {
    public String name() { return "C-" + super.name(); }
}
// Usage:
C c = new C();
System.out.print(c.name());

What is printed?

A
$C-A$
B
$A-B-C$
C
$C-B-A$
check_circle
D
$C$

Explanation

C calls super.name() which is B's, prepending "C-". B calls super.name() which is A's, prepending "B-". Result: "C-B-A".
