(a) fix the bug on the feature branch and "try to get them both deployed together"
(b) git stash, fix the bug in a new branch, come back
(c) locally clone the repository
At least (b) is somewhat sane, but it's still weird that the even more code-managementy option of "commit your halfway feature work/create new branch for the bugfix/come back to the feature and amend/squash/soft reset" isn't even mentioned.
Your cases are more involved than the contrived scenario you give, where their weird options don't make sense.
No, option 2 is to stash.
Their three weird options are:
(a) fix the bug on the feature branch and "try to get them both deployed together"
(b) git stash, fix the bug in a new branch, come back
(c) locally clone the repository
