A) Encapsulation is the isolation of portions of code so that they cannot be accidentally modified; inheritance provides for code reuse; polymorphism provides for one-name, many semantics. Abstraction is a useful attribute, but it is not a mechanism. Recursion is a control structure, providing for a different way to express looping or repetition.
