You should assume the presence of other appropriate fields and methods. Each car can be built to one of three trim levels: base, luxury or sport. They can also be configured with an electric or petrol engine. a. Write a program to implement the given scenario. Car +getTrimLevel() BaseCar SportCar LuxuryCar Engine +accelerate() +getFuelLevel() ElectricEngine PetrolEngine b. The manufacturer decides to offer a vehicle with a hybrid engine that is both an electric engine and a petrol engine. Make changes in code as well as UML (Draw the new UML) to achieve the effect of multiple inheritance for HybridEngine. C. Write a test class to test your system.
