Davos, where the annual meeting of World Economic Forum is held, is located in

Concept: The World Economic Forum (WEF) is an international organisation that brings together political and business leaders for policy dialogue. Its flagship event, the WEF Annual Meeting, is traditionally convened at a fixed host town rather than a rotating venue, and identifying the country of a landmark event's traditional host location is a standard static general-knowledge skill.

Application: Davos is a mountain resort town in the canton of Graubunden in eastern Switzerland. Since the WEF's founding in 1971, the Annual Meeting has traditionally convened in Davos each January, with only rare exceptions (for instance, the 2002 meeting was held in New York City). This is why the event is often informally called the "Davos summit". Since Davos itself lies within Swiss territory, the country being asked for is Switzerland.

Cross-check: Each other offered country can be checked and ruled out on its own facts:

• France is a Western European country whose capital is Paris; the town of Davos does not lie within France.

• Germany is a Central European country whose capital is Berlin; the town of Davos does not lie within Germany.

• Luxembourg is a small Western European country whose capital is Luxembourg City; the town of Davos does not lie within Luxembourg.

Result: So, among the given options, Davos is located in Switzerland.
