Explanation:

In the context of geopolitical systems and globalization:

1. Bilateralism represents the lowest level of globalization - cooperation between just two countries
2. Regionalism represents a moderate level - cooperation among countries within a specific geographic region (e.g., EU, NAFTA, ASEAN)
3. Multilateralism represents the highest level - cooperation among many countries across different regions, often on a global scale (e.g., WTO, UN, IMF)

Therefore, the correct ranking from lowest to highest level of globalization is: Bilateralism → Regionalism → Multilateralism.

This progression reflects increasing complexity, scope, and geographic reach of international cooperation arrangements.
