The three main programming mechanisms that constitute object-oriented programming are encapsulation, inheritance, and polymorphism. Encapsulation refers to the practice of data and methods being kept within a single class or object, while inheritance allows for the creation of new classes based on existing ones. Polymorphism allows for different objects to be treated as if they were the same type, enabling flexibility and simplifying code. Option B is close but misses out on polymorphism. Option C mentions recursion, which is not a main programming mechanism of object-oriented programming, while option D replaces encapsulation with abstraction.
