Which of the following statements about floods in Bihar are correct?
1. Bihar is basically a plain area
2. Major rivers in Bihar are long with catchment in mountains
3. Bihar is economically backward
Out of these:

Correct option is C

The correct answer is (c) All the three are correct

Explanation:

• Statement 1 is correct: Bihar is part of the Indo-Gangetic plain, which is very flat, leading to poor drainage and waterlogging.
• Statement 2 is correct: Rivers like the Kosi, Gandak, and Ghaghara originate in the Himalayas (Nepal). Heavy rainfall in these mountains causes sudden discharges into the Bihar plains.
• Statement 3 is correct: Economic backwardness hampers the ability to build and maintain high-quality flood-control infrastructure and disaster management systems.
• The Kosi River is known as the "Sorrow of Bihar" due to its frequent course changes.
• Almost 73% of Bihar's geographical area is flood-prone.

• Bihar is the most flood-affected state in India.
• Flood management is difficult because many river catchments lie outside Indian borders in Nepal.

• These are incomplete as they fail to recognize all the interconnected geographical and socio-economic factors that contribute to the flood crisis in Bihar.
