Correct Answer:
C. Durand Line
The correct answer is the Durand Line. The Durand Line is the 2,640-kilometer (1,640 mi) international land border between Pakistan and Afghanistan. It was established in 1893 by Sir Mortimer Durand and Abdur Rahman Khan, the then-Amir of Afghanistan.
- LOC (Line of Control): The Line of Control is the de facto military control line between the Indian and Pakistani parts of the former princely state of Jammu and Kashmir.
- Taftan: Taftan is a border town in Balochistan, Pakistan, near the border with Iran, not the name of the border itself.
- None of these: This is incorrect as the Durand Line is the recognized border.
Understanding the names of international borders is fundamental to regional geography and political history.
