Suppose you have a git repository and edited an existing (previously committed) file called README.md. Which one of the following comands will not work (as intended)? Select one: a. git status to see the list of what files has been modified since the last commit. O b.git diff README.md to see the exact changes in the README.md file compared to its version at the last commit. .git add README.md for staging the README.mdfile for the next commit. O d.git commit-m "edited the readme file" to commit the changes made since the last commit including the changes to README.md file
