The correct answer is C. Both A and B . Digital tools that facilitate project team collaboration can include agenda management tools, teleconferencing platforms, document-sharing websites, planning software, digital collaboration platforms, and social media or enterprise social tools. These tools support different collaboration needs. Agenda management helps structure meetings and decision points. Teleconferencing enables remote interaction and real-time discussion. Document-sharing websites support version access, review, storage, and team visibility. Planning software helps coordinate schedules, tasks, dependencies, resources, and progress. Digital collaboration platforms support messaging, shared workspaces, issue tracking, knowledge exchange, and team coordination. Social media or enterprise social tools can support rapid communication, community building, informal updates, and engagement, where appropriate and controlled. Option A is correct but incomplete. Option B is also correct but incomplete. The question asks which digital tools can be used, and both groups contain valid examples. Effective project managers select tools based on information sensitivity, stakeholder needs, accessibility, governance requirements, team distribution, and the complexity of collaboration. The uploaded source question lists both tool groups and provides “Both A and B” as the complete answer option.
