If you didn't retake the same course that you were so close to getting at least the C in, I'd question judgment and look at it is if you were taking the easy way out. I dont believe it would be in the way of offering an interview, but if it was me interviewing you, I'd possibly bring it up. If someone were to bring it up (if you took the easier course), how would you answer? Rhetorical question for you to think about - doesn't require you to respond answering here.
TLDR is to repeat the same course in this case.
