Multilevel inheritance allows _________________ in the program.

Multilevel inheritance allows a class to be derived from a class which is itself derived from another class. This means that a class can inherit properties and methods from a parent class (base class), and that parent class can also inherit from its own parent class. This creates a 'chain' or 'hierarchy' of classes, where a subclass can inherit characteristics from multiple levels of parent classes in the program. This can be useful for creating more specific subclasses from general parent classes, while still maintaining a logical structure of inheritance.
