All four questions are explicitly associated with the Scrum of Scrums (SoS) Meeting. The purpose of the meeting is to coordinate multiple Scrum Teams working on the same large project or on strongly interdependent work.

SCRUMstudy lists all four questions: what the team has worked on since the previous meeting; what it will work on before the next meeting; what other teams expected it to finish that remains incomplete; and what upcoming activities might affect other teams.

The first two provide cross-team visibility into progress and upcoming activity. The third exposes delayed inter-team dependencies. The fourth identifies potential future conflicts, shared-resource issues, interface changes, or other work that can affect neighboring teams.

These questions make SoS more than a status meeting. They support dependency management, early risk identification, integration, transparency, and coordination across team boundaries. The Chief Scrum Master, or another facilitating Scrum Master, normally facilitates the meeting.

Since I, II, III, and IV are all standard SoS questions, D is correct.
