Which option is necessary for collaboration when multiple developers are working on the same project in Mendix?

Version control methodology is essential for collaboration when multiple developers are working on the same project in Mendix because it provides a systematic way to manage changes to the project's codebase. This methodology allows developers to work on different features or fixes concurrently without interfering with each other's work. With version control, changes made by one developer can be tracked, merged, or reverted as necessary, ensuring that the project remains stable and up to date.

Additionally, version control helps prevent conflicts that arise when two or more developers attempt to modify the same part of the code simultaneously. It provides a history of changes, which enables teams to understand the evolution of the project, revert to previous versions if needed, and coordinate work more effectively. This is particularly crucial in a collaborative environment where proper communication and organization among developers are key to maintaining productivity and minimizing errors.
