Answer:
Race race = new Race(track, car);
Step-by-step explanation:
Complete code fragment is as follows:
Track track = new Track();
Car car = mycar;
Race race = new Race(track,car);
Here we are declaring a variable race of the type Race which is initialized to new instance of Race class. The constructor of race takes up the following 2 arguments:
1) New Instance of Track class;
2) Previously defined reference to an object of type Car.
