Correct Answer: The program will output: Base Derived
Correct Answer: True
Explanation:
Multiple inheritance means deriving a class from more than one classes. On the other hand, multiple levels of inheritance means a class has been derived from a base class and the base class itself has been derived from another base class. Multiple inheritance is not permitted in C#.NET.
Correct Answer: StackMemoryException
