What best defines a global supply chain?

A global supply chain can best be defined as the process of production and distribution across international borders. This definition encompasses the intricate networks of suppliers, manufacturers, and distributors that operate in multiple countries to source materials, produce goods, and deliver them to consumers worldwide.

The global supply chain reflects the interconnectedness of economies and the necessity for businesses to coordinate activities across various geographical locations, enabling them to optimize resources, reduce costs, and improve efficiency. This process involves not only logistics and transportation but also integration of different production processes, adherence to international regulations, and collaboration with various stakeholders across different nations.

The other options focus on localized or domestic aspects, which do not accurately encompass the scope of a global supply chain. For instance, local suppliers, domestic logistics, and sales aspects alone do not illustrate the entirety of the complex, cross-border activities inherent in a global supply chain.
