Question on Integration Management

Guys Help me understand how to answer this question.

 

You have assembled a core team to develop the project management plan for the next generation of fatigue fighting drugs. The science is complex, and the extended team of researchers, clinicians, and patients for trials exceeds 500 people. The content of your project management plan will be directed primarily by two factors. They are—
a. Project complexity and the capability of resources
b. Number of resources and project schedule
c. Team member experience and budget
d. Application area and complexity

I guess so.. D. Application area and complexity

I have not got any such questions in my exam as well as in Mock test.

The Answer is D .Why becuase Application area and complexity are reasonse for selecting which processes to add to the Project Mamagement Plan during Develop Project Planning , or for any plan really.

PMBOK 5ed Page 74 "The project management plan content will vary depending upon the application area and complexity of the project"

Thanks for the explanation.. Yes the right answer is D
