Object-oriented concepts: Does multiple inheritance allow a class to inherit from more than one superclass?

Introduction / Context:
Inheritance is a core object-oriented mechanism for reusing behavior and structure. In languages that support multiple inheritance, a class can extend more than one parent, combining capabilities across hierarchies. Understanding this model helps clarify differences among languages and when to use composition or interfaces instead.

Given Data / Assumptions:

• Some languages (C++, Python) support multiple inheritance.
• Others (Java, C#) restrict classes to single inheritance but allow multiple interfaces.
• Design choices impact method resolution and diamond-shaped hierarchies.

Concept / Approach:
Multiple inheritance enables a subclass to inherit attributes and methods from multiple superclasses. This can reduce duplication but introduces complexity: name clashes, ambiguous base methods, and the diamond problem. Languages address these issues via linearization (Python’s MRO), virtual inheritance (C++), or by avoiding multiple concrete inheritance entirely and favoring interfaces or composition.

Step-by-Step Solution:
Identify whether the target language supports multiple inheritance.If supported, define the subclass extending multiple parents and resolve conflicts explicitly.If not supported, model shared behavior with interfaces or composition.Test method resolution order to confirm expected overrides.Document design rationale to aid maintainers.

Verification / Alternative check:
Create a minimal example with two parents providing the same method name and observe how the language resolves the call path (e.g., Python MRO), confirming how multiple inheritance functions.

Why Other Options Are Wrong:
Incorrect: denies the standard definition of multiple inheritance.Only procedural or “no interfaces” scenarios: orthogonal to inheritance capability.

Common Pitfalls:
Overusing inheritance where composition would suffice, creating fragile hierarchies, and neglecting clear override resolution.

Final Answer:
Correct
