Inheritance Class Object Polymophism Instance variable [Choose ] ✓ It is any variable that does not represent a living being. It allows properties and functions to be passed to another object when an object is deleted. It represents a blue print of an object. It is like a global variable that can be accessed in all functions of a program. It is a category to organize variables and objects in groups. It is an instance of a class. It is a programming command with a special meaning. Classes can acquire properties and functions from other classes. It is a property inside that class that exists throughout the lifetime of an object. It is used to define the relationship between classes. It is a variable of a primitive type. It is a variable that can store values of multiple types. It allows a variable of a super class type to be assigned an instance of a subclass type.
