Extension of the International boundaries of India along with their neighbouring countries in ascending order are
- (a)China, Bangladesh, Pakistan, Nepal
- (b)Nepal, Pakistan, China, Bangladesh
- (c)Nepal, Pakistan, Bangladesh, China
- (d)Pakistan, Nepal, China, Bangladesh
Correct — B, 'Nepal, Pakistan, China, Bangladesh.' Ordered by the length of India's land border with each (ascending): Nepal about 1,751 km < Pakistan about 3,323 km < China about 3,488 km < Bangladesh about 4,097 km, which is India's longest land border. Only option B lists them shortest to longest.
- (a)China, Bangladesh, Pakistan, Nepal — This is close to the reverse order — it starts with China, puts Bangladesh (the longest) second and Nepal (the shortest) last, which is not ascending.
- (c)Nepal, Pakistan, Bangladesh, China — Correct at the start, but it wrongly puts Bangladesh before China; in fact China (about 3,488 km) is shorter than Bangladesh (about 4,097 km).
- (d)Pakistan, Nepal, China, Bangladesh — Swaps the first two: Nepal (about 1,751 km) is shorter than Pakistan (about 3,323 km), so Nepal must come first.
Lengths of India's land borders with its neighbours (Ministry of Home Affairs figures). In descending order: Bangladesh (~4,097 km) > China (~3,488 km) > Pakistan (~3,323 km) > Nepal (~1,751 km) > Myanmar (~1,643 km) > Bhutan (~699 km) > Afghanistan (~106 km). Among the four asked, ascending order is Nepal < Pakistan < China < Bangladesh.
Two anchor facts crack it — Bangladesh has India's longest land border, and Nepal's is the shortest of the four listed. Fixing Bangladesh last and Nepal first eliminates every option but B. Watch the close China–Pakistan pair (3,488 vs 3,323 km).
- Bangladesh: about 4,097 km — India's longest land border
- China: about 3,488 km
- Pakistan: about 3,323 km
- Nepal: about 1,751 km — shortest among the four listed
- Ascending order asked: Nepal < Pakistan < China < Bangladesh
- Confusing 'ascending' with 'descending' order
- Swapping China and Bangladesh, or Nepal and Pakistan, whose lengths are commonly mixed up
MPPSC and UPSC ask which neighbour shares the longest/shortest border with India, or to arrange the borders in order of length.
