Final answer:
The incorrect reason listed for the importance of organizing is 'd. Organising inspires and motivates employees,' since motivating employees is more related to leadership and management than to the function of organizing itself.
Step-by-step explanation:
The reason for the importance of organizing that is not listed among the options provided is d. Organising inspires and motivates employees, especially if the employees can perceive a specific link between their performance and the rewards they receive. While organizing does have a positive effect on employees by providing structure and clarity, direct motivation and inspiration are more often the result of leadership, company culture, or individual management styles rather than the organizing function itself. Organizing is fundamentally about arranging the structural elements of an organization to ensure that jobs are allocated, resources are managed efficiently, and procedures are in place to ensure a smooth operation. Therefore, the correct answer is d, as organizing is specifically responsible for division of labor, efficient resource utilization, and systematizing tasks and resources, not directly for inspiring and motivating employees. The latter can be an indirect outcome of a well-organized workplace, but it is not the primary purpose or function of organizing.
