Which countries share a border with Afghanistan?

The response indicates that the correct answer is accurate because Afghanistan shares borders with Iran, the People's Republic of China, and Pakistan. Understanding the geographical context is crucial here.

Iran lies to the west of Afghanistan, creating a direct border that is significant for both historical and contemporary reasons, including trade and cultural exchange. The People's Republic of China shares a very brief border with Afghanistan through the Wakhan Corridor, which connects the two nations and demonstrates Afghanistan's strategic location in Central and South Asia. Additionally, Pakistan shares a long and critical border with Afghanistan to the south and southeast, which has substantial implications for politics, security, and migration in the region.

In contrast, the other options include countries that may be geographically or politically relevant to Afghanistan but do not accurately reflect the actual border situation. For example, while India shares a close relationship with Afghanistan, it does not share a direct border. Understanding which countries directly border Afghanistan is key to grasping its geopolitical significance in South and Central Asia.
