To answer this question, let's analyze each class and determine whether instances of these classes can be serialized:
Option A) Car - This option is correct because the class Car extends Vehicle and implements Serializable. When a class implements the Serializable interface, it indicates that instances of that class can be serialized.
Option B) Ford - This option is correct because the class Ford extends Car. Since Car can be serialized, any subclass of Car, such as Ford, can also be serialized.
Option C) Dodge - This option is incorrect because the class Dodge extends Car, which can be serialized. Therefore, instances of the Dodge class can also be serialized.
Option D) Wheels - This option is incorrect because the class Wheels does not implement the Serializable interface. Therefore, instances of the Wheels class cannot be serialized.
Option E) Vehicle - This option is incorrect because the class Vehicle does not implement the Serializable interface. Therefore, instances of the Vehicle class cannot be serialized.
The correct answers are options A (Car) and B (Ford) because instances of these classes can be serialized.
