Consider the following class definitions: class bClass
{
public:
void setX(int);
void print() const;
private:
int x;
};
class dClass: public bClass
{
public:
void setXY(int, int);
void print() const;
private:
int y;
};

Which of the following statements correctly redefines the member functionprint of bClass?

a. void dClass::print() const {

dClass:print();

cout << " " << y << endl;
}

b. void dClass::print() const {

cout << x << " " << y << endl;
}

c. void bClass::print() const {

cout << x << " " << y << endl;
}

d. void dClass::print() const {

bClass::print();

cout << "y = " << y << endl;

}
