Thanks Harry! That's what I thought when I read the question again and again. However, Pmbok then confused me.
I think questions like this trick us in exam so have to be extra careful when answering and look for key words.

Geeta:

This one is kind of a tricky question, but it hinges on the phrase, "completed all milestones." That means that you've already verified desiderables and they have been accepted - so you're out of M&C. The best answer is "Closing."

Harry

You are managing a software development project with a set of preplanned milestones. Your team has completed all milestones and you are now verifying that the product meets the specifications outlined in the project management plan. What process group are you currently in?

Monitoring and controlling

Closing


I chose m&c as per PMBOK but i found answer as closing. Can anyone pls advise?
Thanks!
