Final answer:
A. The legal department is usually thought of as a staff function in an organization, while the operations management, finance department, and marketing department are considered line functions.
Step-by-step explanation:
In an organization, the legal department is usually thought of as a staff function.
This department provides legal advice, handles legal matters, and ensures compliance with laws and regulations. They work in support of the other departments within the organization but may not directly contribute to the core operations of the business.
On the other hand, the operations management, finance department, and marketing department are considered line functions as they directly contribute to the production, management, and promotion of goods or services offered by the organization.
