Identify the one correct statement regarding the reason for the interaction of the 5 process groups defined by the PMBOK Guide [e.g. IPECC].

a) Initiating and Executing don't interact since you have to plan before you can execute.

b) Planning and Monitoring & Controlling never interact since you are planning within both of those groups.

c) Executing and Closing don't interact since you cannot move directly from executing on a project to closing a project down.

d) Initiating and Closing don't interact since you must plan, execute and control the project before you are ready to close it down. Also, there is no direct output from initiating that you would use as an input for the closing process.
