The answer is C: Improved production and transportation.
Communication systems play a key role in improving production and transportation, allowing for faster and more efficient communication between different parts of a supply chain. This can result in improved productivity, as well as faster and more accurate information sharing, which can lead to more efficient decision-making processes. Improved communication systems are also critical in the efficient transportation of goods, which can lead to cost savings and faster delivery times.
While communication systems can have an impact on economic growth and outsourcing, they are most closely associated with improved production and transportation systems.
