How can you synchronize changes between branches in Git?

Merging one branch into another is the most effective way to synchronize changes between branches in Git. This process involves integrating the different changes made in two separate branches, allowing for a cohesive development workflow. When you merge, Git reconciles the differences between the branches, creating a new commit that has two parent commits, preserving the history of both branches.

Merging is particularly useful when you want to combine the work of multiple contributors, each working on different aspects of a project, into a main branch. It helps maintain a clear project history and avoids the complications that may arise from arbitrary changes.

Other options don't provide the same level of effectiveness or are not suitable for synchronizing changes. Simply deleting and recreating a branch would result in the loss of all its history and changes made, which does not facilitate synchronization. Pushing changes to a remote repository is about sharing changes rather than harmonizing them between branches. Directly editing files in both branches could lead to inconsistencies and conflicts, making it an impractical approach compared to the merging strategy.
