The correct answer is: a) Upper Assam
Upper Assam is the most flood-prone region in Assam. The Brahmaputra River, which flows through the region, is prone to flooding during the monsoon season. The floods can cause widespread damage to crops, infrastructure, and homes.
Lower Assam is also prone to flooding, but to a lesser extent than Upper Assam. The Brahmaputra River also flows through Lower Assam, but the floods are not as severe as in Upper Assam.
The hilly regions of Assam are not as prone to flooding as the plains. However, the hilly regions are prone to landslides, which can also cause widespread damage.
Along state borders is not a correct answer. The areas along state borders are not more prone to flooding than other areas in Assam.
Here are some additional details about the flooding in Assam:
- The Brahmaputra River is the main river in Assam. It is the longest river in India and the ninth longest river in the world.
- The Brahmaputra River is prone to flooding during the monsoon season. The monsoon season is from June to September.
- The floods can cause widespread damage to crops, infrastructure, and homes.

- Building embankments along the Brahmaputra River.
- Relocating people living in flood-prone areas.
- Providing relief to people affected by floods.
- However, more needs to be done to mitigate the effects of flooding in Assam.
