Sorry, too many actions in one question. First, any time you see a question that has ALL inclusive terms - it's just a bad question. The correct answer would be "It depends."
If corrective and defect repair is because of issues within the design then most likely yes a CR is needed. If it's because a work didn't follow the work instructions, then No CR is needed. I would review Pg 353 or the PMBOK Guide. If the question is about contingency and workarounds, yes a CR is needed.
Hope this helps
