A developer is working with a class hierarchy: class A, class B(A), and class C(B). They need to verify that class C has access to a method defined in class A. Which check correctly confirms this?

C.__bases__[0].__dict__['method_from_A']

Which statement correctly describes the behavior of hasattr() when checking an object for an attribute?

It returns True only if the attribute is defined directly in the object's class.

It returns True if the attribute exists on the object, including attributes defined on the instance and class attributes.

It returns True only if the attribute is defined in the object's __dict__.

It raises an AttributeError if the attribute is not found.

What is the primary purpose of introspection in Python?

To optimize the performance of loops and recursive functions

To convert Python source code into bytecode before execution

To examine the properties and behavior of objects and classes at runtime

To enforce type checking at compile time
