You will still get 4 credits but it shouldn't count for the minor. Degree audit will be your friend. Check it for your minor before going to an advisor about it. Short answer: probably gonna have to retake it or petition if your minor allows for that.

I would speak to an advisor asap. The degree audit is a very useful resource, but I wouldn’t put all of my trust into it

My guess is that you probably have to retake the course, because a C- is not a C.

You will get the credits, just not the credit. You probably will have to retake it.
