Question

Doab is made up of___________
A. Two words
B. Three words
C. One words
D. Four words

Answer 1

Hint: The word Doab is formed in the same way as the word Punjab—Punj' means five and 'ab' means water. Doab is the tract of land between two converging rivers. The Indus and its tributaries form many doabs in the northern plains.

Complete answer:
 Doab is a term used in South Asia particularly in India and Pakistan to refer to " tongue" or tract of land lying between two converging rivers. The Northern plains formed by Indus and its tributaries— the Jhelum, the Chenab, the Beas, the Ravi, the Sutlej are dominated by doabs.
The Ganga and Yamuna Doab region forms the Indo- Gangetic trough. The region enclosed by this Doab are of two types- one is khadir also termed as Nali in northern India. These are floodplains with new soil deposits every year and are ideal for intensive agriculture. That's why this region is dominant in agricultural activities due to its highly fertile soil and is the most densely populated region in India. The other one is a bhangra that has a terrace-like structure. These are plains lying away from the floodplains and so are less fertile compared to khadi.
Punjab Doabs are formed by rivers in the Punjab region of Pakistan. It has distinct names in India which are said to have been coined by Todar mal, a minister of Akbar. The first letter of these names is Persian alphabets except the Sindhu Sagar Doab.
The names are-
Sindhu Sagar Doab that lies between Indus and Jehlum
Jech Doab - lies between Jhelum and Chenab.
Rachna Doab-lies between Chenab and Ravi
Bari Doab- lies between Beas and Ravi
Best Doab - lies between Beas and Sutlej
The meaning of Doab lies within its formation, that is the region enclosed by the convergence of two rivers. Doab is made up of two words — 'do' means two and 'ab' means water.
So, the correct answer is Option A.

Note: Doab refers to the region of confluence between two rivers. The Northern plains including the regions of India and Pakistan are dominated by Doabs. These are lifelines in the northern plains as they are a major source of living for farmers.
