What is the primary purpose of tools included in an IDE?

The primary purpose of tools included in an Integrated Development Environment (IDE) is to integrate various programming tasks. An IDE provides a centralized platform where developers can write, test, debug, and manage their code. The tools typically found in an IDE, such as code editors, compilers, debuggers, and version control systems, work together seamlessly to streamline the development process. This integration allows developers to perform multiple programming tasks efficiently without needing to switch between different applications, thereby improving productivity and simplifying the workflow.

The other options do not correctly capture the main function of IDEs. For instance, while some IDEs may help to minimize code through tools like auto-completion, this is not their primary purpose. Similarly, increasing complexity is contrary to the goal of most IDEs, which strive to simplify coding tasks. Promoting collaboration is a valuable feature but is secondary to the core integration of development tasks that an IDE offers. Thus, integrating various programming tasks stands out as the central function of an IDE.
