Which of the following function declarations would be correct to overload the multiply operator for the Rational numbers class?
A) friend Rational operator timesconst Rational &left, const Rational &right);
B) Rational operator timesconst Rational &left, const Rational &right);
C) friend Rational operator *const Rational &left, const Rational &right);
D) Rational operator *const Rational &left, const Rational &right);

To overload the multiply operator for the Rational numbers class, we need to define a friend function that takes two Rational number objects as arguments and returns a Rational number object. The function should have the signature `friend Rational operator*(const Rational& left, const Rational& right)`.

Option A is incorrect because the function should not be declared as a friend in the function signature.

Option B is incorrect because the function should be defined as a friend function outside the class definition.

Option D is incorrect because the function should not have the `const` qualifier in the function signature.

Therefore, option C is the correct choice.
