Final answer:
IDE stands for Integrated Development Environment, which includes tools like a source code editor, build automation tools, and a debuger to facilitate software development (option 4).
Step-by-step explanation:
IDE stands for Integrated Development Environment. It is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools, and a debuger. By integrating these tools into a single graphical user interface (GUI), an IDE improves productivity by simplifying the tasks involved in software development, such as writing, testing, and debuging code.
