Siliguri corridor also known as chicken neck has average width of ______.

Concept

The Siliguri Corridor, nicknamed the “Chicken’s Neck,” is a narrow strip of land in West Bengal that is India’s only land link between the main landmass and the eight North-Eastern states. It is wedged between Nepal, Bhutan and Bangladesh, which is why its width is a strategic concern. A “corridor” in geography is a constricted passage of territory connecting two larger regions, so the question is asking for the typical average breadth of this passage.

Application

Standard geography references put the average width of the Siliguri Corridor at about 21 km (its constricted stretch is generally described as roughly 20–22 km across). Among the four choices, the breadth that matches this documented dimension is 21 km.

Cross-check

• 21 km is the value standard references quote as the corridor’s average width.

• 41 km and 80 km describe breadths far larger than the documented corridor — too wide to form a “neck.”

• 6 km describes a corridor much thinner than the recorded dimension.

Hence the average width of the Siliguri Corridor is 21 km.
