Correct Answer:
B. China
Kashgar is a historic oasis city located in the Xinjiang Uyghur Autonomous Region of China. It holds immense strategic importance due to its geographical position at the western end of the Tarim Basin, near the borders with Kyrgyzstan, Tajikistan, and Afghanistan. Kashgar was a crucial trading hub on the ancient Silk Road, connecting China with Central Asia and the Middle East. Therefore, it is unequivocally a city within China. The other options—India, Pakistan, and Afghanistan—do not contain the city of Kashgar, making them incorrect.
