Which of the following Isthmuses has been known as the 'Devil's Neck?

Correct answer: (a) Kra Isthmus

Explanation

An isthmus is a narrow strip of land that connects two large landmasses and separates two water bodies. The Isthmus of Kra is located in Southeast Asia, in Thailand, as a narrow land strip between the Malay Peninsula and the mainland of Southeast Asia. Because the Isthmus of Kra is very narrow and has been a hindrance to maritime routes, it has been nicknamed the “Devil’s Neck”.
