Which of the following is a challenge faced by global supply chains?

Geopolitical risks are indeed a significant challenge faced by global supply chains. These risks arise from political instability, conflict, or changes in government policies that can affect trade relationships and the movement of goods across borders. For instance, tariffs may be imposed during trade disputes, leading to increased costs and delays in deliveries. Additionally, shifts in foreign relations or regulatory environments in different countries can create uncertainty for businesses relying on global supply chains, making it difficult to plan and execute operations effectively.

On the other hand, standardized regulations could potentially simplify operations across borders, while decreased product variety is more of a strategic decision than a challenge. Consistent consumer behavior may vary, but it is not inherently a challenge unique to global supply chains. Hence, geopolitical risks stand out as a prominent challenge that companies must navigate to ensure efficiency and reliability in their operations.
