Which is the correct code that returns a complex number that is the complex conjugate of this one?

Complex.prototype.conj = function() { return Complex(this.r, -this.i); };

Complex.prototype.conj = function() { return new Complex(this.r, -this.i); };

Complex.prototype.conj = function() { return (this.r, -this.i); };

Complex.prototype.conj = function() { new Complex(this.r, -this.i); };
