Countries relying on each other for goods, services, or resources

• A. Interdependence
• B. Incentive
• C. International Cooperation
• D. Landlocked

Answer: (A)

Interdependence describes mutual reliance among countries for goods, services, and resources. When economies specialize and trade, each country becomes dependent on others to obtain what it doesn’t produce efficiently, creating a web of reciprocal connections. This fits the statement because it emphasizes that nations rely on one another, not just a desire to act together or a geographic situation.

Incentive refers to motivation behind actions, not the actual state of dependence. International cooperation is the process of working together, which can result from interdependence but is about actions rather than the existing mutual reliance. Landlocked describes a geographic condition that affects access to trade routes, not the broader pattern of mutual dependence between nations.
