Final answer:
Both primary and support activities are essential for a business's productive capacity and operations. Primary activities directly produce goods or services, while support activities ensure these operations are effective. A software developer would work in the quaternary sector, which is part of the service sector.
Step-by-step explanation:
To provide productive capacity and keep the business in operation, both primary activities and support activities are required. Primary activities relate to the core operations of an organization that are directly involved in producing goods or services, while support activities are those that provide the necessary background to the primary activities, ensuring that operations run smoothly.
For example, in an economy, the primary sector involves the collection of raw materials such as agriculture and mining, and the secondary sector involves manufacturing these materials into finished goods. The tertiary sector includes services such as retail and healthcare, and the quaternary sector deals with information handling and processing, which would encompass the role of a software developer. Therefore, the correct answer to the question is (c) Both primary and support activities.
