The Retrospect Project Meeting is the meeting described in the relevant SBOK edition as not Time-boxed and capable of being conducted either in person or virtually. Its objective is broader than a Sprint-level retrospective: participants evaluate the overall project, document lessons learned, discuss positive and negative experiences, and identify opportunities to improve future projects.

SCRUMstudy specifically describes this meeting as not being Time-boxed and notes that it may take place physically or in a virtual format.

The other choices are Time-boxed Scrum events. The Daily Standup has a strict short duration. Sprint Planning is Time-boxed according to Sprint length, and Sprint Review/Demonstrate and Validate Sprint is also conducted within a defined time-box.

The rationale is that Retrospect Project occurs after the broader project lifecycle and may involve examining substantial lessons, organizational practices, knowledge transfer, transition matters, and stakeholder feedback. It therefore does not carry the same fixed execution-cycle constraint as recurring Sprint events.

Accordingly, the correct answer is B.
