git cherry-pick -n <commitA>

This command applies the changes introduced by the specified commit to the current branch.

The -n or --no-commit option makes git apply the changes of the given commit hash to the working tree and the index, but does not make a new commit.

This is particularly useful if you need to slightly modify the changes from <commit-hash> before committing or if you want to apply the changes from multiple commits before making a commit.

If you want to automatically create a new commit with picked changes, you can just use git cherry-pick <commit-hash> without the -n flag.
