Object-Oriented Programming (OOP) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Object-Oriented Programming (OOP) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Object-Oriented Programming (OOP) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.

Why not A: “A keyword used in a subclass to refer to members or methods of its immediate parent class.” does not fit this question. The answer is A special method automatically invoked when an object is destroyed, used to release resources..
- B. A mechanism where the method to be executed is determined at compile time based on the object's declared type.
Why not B: “A mechanism where the method to be executed is determined at compile time based on the object's declared type.” does not fit this question. The answer is A special method automatically invoked when an object is destroyed, used to release resources..
