The Shape class is defined as follows:

public class Shape {
    private String name;

    public Shape(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

Which of the following will properly create a Circle class that is a subclass of the Shape class? A Circle is a Shape and has a radius as well as a getRadius method.
