Solution
The correct option is A Chos
Punjab spans three physiographic regions, the smallest being the Siwalik Range in the northeast, where elevations reach about 3,000 feet (900 metres).
Farther south, the narrow, undulating foothill region is dissected by closely spaced seasonal torrents, locally known as chos, several of which terminate in the plain below without joining any stream.
There are large numbers of seasonal hill torrents which leave the Siwalik Range and enter the level plain.
These torrents are swollen with water soon after heavy showers in the neighbouring hills and carry with them a heavy load of coarse sand and silt.
They are furious when rushing to the plains.
They are called ‘chos’ in the plain where their beds are broad, braided, shallow and sandy.
They are quite numerous and in some places every kilometre has a ‘chos’.
