Correct Answer:
B. 3000 km
The correct answer is 3000 km. The proposed motorway from Gwadar to Kashgar is a crucial component of the China-Pakistan Economic Corridor (CPEC), a flagship project of China's Belt and Road Initiative. This extensive network aims to connect Gwadar Port in Balochistan, Pakistan, to Kashgar in Xinjiang, China, facilitating trade and regional connectivity. The approximate length of this route is indeed 3000 kilometers, encompassing various infrastructure developments including highways and railways. Distractors like 2800 km, 2000 km, and 2600 km are incorrect as they do not reflect the actual planned length of this significant economic corridor.
