Consider the following statements. public class Circle {private double radius; public Circle() {radius = 0.0;} public Circle(double r) {radius = r;} public void set(double r) {radius = r;} public void print() {System.out.println(radius + " " + area + " " + circumference);} public double area() {return 3.14 * radius * radius;} public double circumference() {return 2 * 3.14 * radius;}} Circle myCircle = new Circle(); double r; Which of the following statements are valid in Java? (Assume that console is Scanner object initialized to the standard input device.) (i) r = console.nextDouble(); myCircle.area = 3.14 * r * r; System.out.println(myCircle.area); (ii) r = console.nextDouble(); myCircle.set(r); System.out.println(myCircle.area());

B) Only (ii)
C) Both (i) and (ii)
