Which role is needed to group related projects and demands?

According to the ServiceNow documentation1, the it_program_manager role is needed to group related projects and demands. This role can create and manage programs, which are containers for projects and demands that share a common goal or objective. The other options are incorrect because:

B. it_project_manager: The it_project_manager role can create and manage projects, but not group them into programs2.

C. it_demand_manager: The it_demand_manager role can create and manage demands, but not group them into programs3.

D. it_project_user: The it_project_user role can view and edit project tasks, but not create or manage projects, demands, or programs4.
