Public inheritance is suitable when you want to create a class that is a more specialized version of another class. This means that the new class inherits the properties and behaviors of the base class, but also adds its own unique features. Option A is incorrect because you would use public inheritance when creating a more specialized version of an existing class, not a completely new one. Option C is incorrect because it mentions modifying a base class, which is not the purpose of public inheritance. Option D is incorrect because public inheritance is used to create a relationship between related classes, not unrelated ones.
