The command to revert to the current stage is-Select one:git checkout .[dot]git checkout masterNone of thesegit checkout <hashvalue>

To determine the correct command for reverting to the current stage in Git, let's analyze the options provided:

1. git checkout .
2. git checkout master
3. None of these
4. git checkout <hashvalue>

Analysis of Options

1. git checkout .: This command checks out all changes in the current directory, reverting any unstaged changes to the last committed state. It effectively reverts the working directory to match the most recent commit.

2. git checkout master: This command checks out the master branch, but it does not revert the current stage. Instead, it switches the working directory to the master branch, which may not be the desired action.

3. None of these: This option suggests that none of the above commands is correct. However, we need to assess if there's a valid command among the options.

4. git checkout <hashvalue>: This command checks out a specific commit identified by the hash value. While it does revert the state to the state at that commit, it does not revert to the current stage unless the hash aligns with the last commit.

Final Answer

The best command to revert to the current stage in Git is:

git checkout .
