Final answer:
Afghanistan is located to the north of Iran. They share a border, and Afghanistan's landlocked position makes it a strategic link in central Asia.
Step-by-step explanation:
The correct statement about the location of Afghanistan in relation to Iran is that Afghanistan is located to the north of Iran. Afghanistan and Iran share a border, with Iran situated to the west and south of Afghanistan. As countries in central and southwest Asia, they both play strategic roles in the region. While Iran has access to the sea, Afghanistan is landlocked and does not have direct access to the sea, making its geography a strategic link between the Middle East and the Far East.
