B. Natural disasters
Explanation
Natural disasters are a major cause of global supply chain disruptions because they can interrupt production, transportation, labor availability, and infrastructure with little or no warning. Events such as earthquakes, floods, hurricanes, wildfires, and severe storms can shut down factories, damage ports, block roads, and delay shipments across entire regions.
Supply chains depend on timing, coordination, and physical movement. When a natural disaster strikes, those conditions break down quickly. A manufacturer may lose access to raw materials if a supplier’s facility is damaged. A shipment may be delayed if a port closes or if rail and trucking routes become unsafe. Warehouses may also face power outages, labor shortages, or inventory losses. Even if the event happens in just one location, the effects can spread through multiple countries and industries because global supply chains are highly interconnected.
This is what makes natural disasters such a serious risk. A single flood in one production hub can delay components needed by factories in other parts of the world. A hurricane near a major shipping route can create bottlenecks that affect delivery schedules far beyond the disaster zone. The result is often higher transportation costs, longer lead times, lower service levels, and pressure on inventory planning.
Option A, increased consumer demand, can create strain, but it is not typically classified as a disruption in the same way as a disaster-driven event. Higher demand may challenge capacity, yet it usually reflects market growth rather than direct operational damage.
Option C, stable political environments, tends to support supply chain continuity rather than disrupt it. Stability usually means fewer policy shocks, fewer border issues, and more predictable operating conditions.
Option D, advancements in technology, generally improve supply chain performance by strengthening visibility, forecasting, automation, and coordination. Technology can help companies respond to disruption more effectively rather than causing the disruption itself.
From a resilience perspective, natural disasters highlight why AI and automation matter. AI can analyze weather patterns, supplier exposure, shipment locations, and historical disruption data to detect risk early. Automated systems can then help companies reroute shipments, rebalance inventory, and shift sourcing decisions more quickly. These tools do not prevent disasters, but they reduce the operational damage by supporting faster and better decisions.
That is why the best answer is B. Natural disasters are one of the clearest and most significant contributors to global supply chain disruption because they directly affect the physical systems that keep goods moving.
