Which of the following is true of object-oriented programming?a.It uses the classical life cycle for software developmentb.It uses UML notations like use case, class, and sequence diagramsc.It uses common processes like analysis, design, and implementation

The correct answer is: b. It uses UML notations like use case, class, and sequence diagrams and c. It uses common processes like analysis, design, and implementation.

Here's why:

a. It uses the classical life cycle for software development - This is not necessarily true. Object-oriented programming (OOP) is a programming paradigm, not a software development methodology. It doesn't prescribe a specific life cycle for software development. The classical (or waterfall) life cycle is just one of many methodologies that can be used in software development, and it's not specific to OOP.

b. It uses UML notations like use case, class, and sequence diagrams - This is true. Unified Modeling Language (UML) is often used in object-oriented design, and it includes notations for representing object-oriented concepts. Use case diagrams represent the functionality of the system from the user's perspective. Class diagrams represent the static structure of the system, including the classes, their attributes and methods, and the relationships between them. Sequence diagrams represent the dynamic behavior of the system, showing the interactions between objects over time.

c. It uses common processes like analysis, design, and implementation - This is true. These are common stages in the software development process, and they are used in object-oriented development just like in other development paradigms. In the analysis stage, the requirements of the system are determined. In the design stage, the system is designed to meet those requirements, often using UML diagrams. In the implementation stage, the design is translated into code.
