11. Can private members be inherited in Python?
- Yes, always
- No, never
- Only if declared as protected
- Through name mangling
12. What is the Method Resolution Order (MRO) in Python?
- Order of method execution
- Order of class inheritance search
- Order of method parameters
- Order of method definition
13. Which attribute shows the MRO of a class?
- __inheritance__
- __mro__
- __order__
- __resolution__
14. What is hybrid inheritance?
- Only multiple inheritance
- Only multilevel inheritance
- Combination of inheritance types
- Only hierarchical inheritance
15. What is the diamond problem in multiple inheritance?
- Memory allocation issue
- Ambiguity in method resolution
- Syntax error
- Import conflict
16. How does Python solve the diamond problem?
- By ignoring one parent
- Using C3 linearization
- By random selection
- By alphabetical order
17. What is the difference between isinstance() and issubclass()?
- No difference
- isinstance for objects, issubclass for classes
- isinstance for classes, issubclass for objects
- Both work the same
18. What is abstract base class (ABC) in Python?
- A class with no methods
- A class that cannot be instantiated
- A class with only variables
- A class that imports modules
19. Which module is used for abstract base classes?
- abstract
- abc
- base
- abstractbase
20. What is the purpose of @abstractmethod decorator?
- To make method private
- To enforce method implementation in subclasses
- To hide method from documentation
- To optimize method performance
