Selected Answer: B
Trick question, but only option B is SPECIFICALLY mentioned in Project+ objectives. Development, testing, and production is for software engineering.

This is a bad question. Ambiguous. Both B and D are theoretically correct.

Agreed. This one is annoying because it requires the reader to assume context. I was originally picking the wrong answer of D, as I'm used to seeing those environments in software engineering scenarios. I think this is a question that was meant more for the PMP...

After reviewing this again, I agree with B. pg. 170 "The Official CompTIA Project+ Guide" - the bottom tier is Data, middle is Application, top tier is Presentation.
