正确答案：(b) The strategic apex is the highest level of the organisation and is therefore the highest level of management. This part ensures that the organisation’s mission is followed and manages the relationship with the environment. The operating core is the part that represents the productive activity of the organisation, gathering inputs and, through conversion, turns them into outputs.The middle line represents that part of the organisation where the middle managers operate. The role of this part is to turn the instructions of the strategic apex into activities for the operating core.The technostructure includes the staff who provide a technical or supportive activity but which are not a part of the core activities. This part of the organisation includes the engineering, accounting and human resource departments.The support staff carry out the ancillary activities that are neither part of the core nor the technostructure. Support staff have no role in the direct activities of the organisation: these activities include catering and public relations.(Students may draw the appropriate diagram)
