SOLID Principles - Quiz

Which principle helps prevent a class from growing large and handling unrelated tasks, leading to maintenance issues?

If a subclass cannot be used reliably in place of its superclass without breaking the system, which principle is violated?

A class depends on lower-level modules and is tightly coupled to a specific implementation (e.g., a concrete email provider). Which SOLID principle is being violated?

You notice an interface with many unrelated methods, leading to classes having unused or empty implementations. Which principle is being violated?

Which concept describes the relationship where one class 'owns' an object and is responsible for its lifecycle?

What is a likely symptom of not following the Open/Closed Principle?

You find yourself adding empty method implementations just to satisfy an interface. Which design principle can help?
