Answer:
The correct answer is (b).
Step-by-step explanation:
A series hybrid car has an electric motor and a gasoline engine, but the gasoline engine does not directly drive the wheels. Instead, the gasoline engine powers a generator that charges the battery, which in turn powers the electric motor.
A parallel hybrid car also has an electric motor and a gasoline engine, but in this case, both the electric motor and the gasoline engine can drive the wheels. This makes parallel hybrid cars more efficient at higher speeds.
So, the main difference between a series and parallel car is that a series car does not use the gasoline engine to run the car, while a parallel car can use both the electric motor and the gasoline engine to run the car.
