Study the following class definition: class Car { public: Car (double speed); void start(); void accelerate(double speed); void stop(); double get_speed() const; private: double speed; }; Which of the following options would make logical sense in the definition of the void accelerate(double speed) function? this->speed = this->speed; speed1 = this->speed; this->speed = speed; this.speed = speed;
