A Subclass, "derived class", heir class, or child class is a modular, derivative class that inherits one or more language entities from one or more other classes (called superclass,base classes, or parent classes). The semantics of class inheritance vary from language to language, but commonly the subclass automatically inherits the instance variables andmember functions of its superclasses.
super class is also known as parent class which is interited ( its property) from child class or drived class.
so here 1. get id is implemented in the superclass
4.get name is implement in the super class.
6. getSalary is an abstract function in the superclass bcoz salary is determined by category.
8. get salay is implement in the sub class.
its true other than this is false. option A is correct.
