A systems administrator wants to check the log of changes made to a Git repository. Which of the following commands can be used for this task?

'git commit log' is not a valid Git command; the correct command to view commit history is `git log`.

The `git branch list` command is not a valid Git command; `git branch` lists local branches.

The `git reflog` command displays a log of all actions that have modified the HEAD of the repository, including commits, merges, rebases, and resets, providing a comprehensive history of local repository changes that affect reference pointers.

'git push log' is not a standard Git command and does not display a log of changes made to the repository.
