Which one of the following is a good alternative to branching and merging in scm?

A good alternative to branching and merging in source control management (SCM) is the use of feature toggles (or flags). This approach allows developers to enable or disable features in the codebase without creating separate branches, facilitating continuous integration and deployment. Feature toggles enable teams to develop, test, and release new features incrementally while maintaining a stable main codebase. This method can enhance collaboration and reduce the complexity often associated with managing multiple branches.
