Inheritance In C Plus Plus — Part 1 MCQs with Explanations

The correct answer is A: private . Let's break down why: In C++, when you inherit a class without explicitly specifying an access specifier (like `public`, `private`, or `protected`), the default access specifier depends on how you inherit. If you use the `class` keyword to derive a class, the default access specifier is private . For example, if you write `class Derived : Base`, it's the same as writing `class Derived : private Base`. If you use the `struct` keyword to derive a class, the default access specifier is public . This means that if you don't write `public`, `protected`, or `private` before the base class name in the inheritance, the members of the base class become `private` in the derived class (when inheriting with `class`). Therefore, the default access specifier is private .
