What type of activities support the primary value activities in the value chain?

The correct answer highlights the role of support value activities in enhancing the effectiveness and efficiency of primary value activities within a business's value chain. These activities are designed to support and amplify the primary processes that directly contribute to creating value for customers.

Support value activities encompass a wide range of operational functions including human resource management, technology development, and procurement. By ensuring that the primary activities—like inbound logistics, operations, outbound logistics, marketing and sales, and service—are optimized and well-resourced, these support activities play a critical role in enabling the overall value creation process.

In contrast, primary value activities focus on the core processes that deliver value to the customer, meaning they do not encompass the range of supportive measures that strengthen and enhance these core activities. As such, while primary value activities are essential, it's the supporting activities that facilitate and improve these processes, driving overall business efficiency and effectiveness.
