In Git, what does the git pull command do?

The git pull command fetches the latest changes from the remote repository and immediately merges them into the current branch. This is a combination of git fetch (which retrieves changes) and git merge (which applies the changes to the current branch). It is commonly used to ensure your local branch is up-to-date with the remote repository. Why other options are wrong: b) Push local changes to the remote repository : This is done with git push, not git pull. c) Delete a branch from the local repository : The git branch -d command is used to delete branches locally. d) Revert changes in the local working directory : git checkout or git reset can be used for this purpose, not git pull. e) Reset the HEAD to a previous commit : The git reset or git revert commands are used to reset the HEAD.
