The correct answer is B.
Look at the order of planning the project the team has chosen. Though understanding the sponsor (choice A) might sound like a good idea, the sponsor is a stakeholder and understanding them is part of stakeholder analysis. That should have occurred before the creation of a WBS. In planning the project, the project scope is defined (choice C is another way of saying finalize the project scope statement) and would come before creating a WBS. Choice D cannot be best as that work does not come next in the process. Other work, like creating a network diagram, should be completed before risk management can effectively be done. Only the activity list (choice B) comes after the WBS and WBS dictionary.
