What is a key benefit of using multiple inheritance in C++?

  1. To allow a class to inherit from a single parent class

  2. To make code more complex

  3. To enable a class to implement multiple interfaces

  4. To solve the diamond problem more efficiently

The correct answer is: To enable a class to implement multiple interfaces

Multiple inheritance allows a class to inherit from multiple parent classes, which provides flexibility and allows for more complex class relationships to be modeled. Option A is incorrect because single inheritance only allows for one parent class. Option B is incorrect because the purpose of multiple inheritance is not to make code more complex, but rather to provide more functionality and organization. Option D is incorrect because the diamond problem can still arise in multiple inheritance, potentially leading to code duplication and other issues. Therefore, C is the best answer as it accurately describes the key benefit of multiple inheritance in C++.
