Sorry Deepak, the question is missing a lot of information (ex. what stage the project is in) in order for us to come up with a correct answer.
I'd suggest getting a high quality simulator product that provide explanations to all answer choices after you complete your mock exam, it will save you much more time to cross reference answers.
What's the answer to this type of question ..
Customer not happy with quality , what should PM do
a. review Quality management plan
b. check Audit report
c. review process and procedures
Apology but I only remember this much of question from my exam.
