The statement "d. It advocates assigning to a multi operating department all major activities" is not true about material management.
Material management does not advocate for assigning all major activities to a multi-operating department. Instead, it involves a systematic approach to planning, organizing, and controlling the flow of materials from their acquisition to their disposal. It also involves coordinating and integrating material-related activities across departments and functions to ensure optimal use of resources, minimize costs, and meet customer requirements.
