The hilly terrain of Manipur leads to many rivers having a:

Fast-flowing character
Meandering course
Braided pattern
Seasonal flow

The correct answer is: Fast-flowing character.

The hilly terrain of Manipur leads to many rivers having a fast-flowing character. This is because the rivers have to flow downhill over a steep gradient. The fast-flowing rivers are often turbulent and can cause erosion.

The other options are incorrect because:

  • Meandering course: This is a type of river course where the river flows in a series of curves. This type of course is more common in flat terrain.
  • Braided pattern: This is a type of river course where the river splits into multiple channels. This type of course is more common in sandy or muddy terrain.
  • Seasonal flow: This is a type of river flow where the river only flows during certain times of the year. This type of flow is more common in arid or semi-arid regions.

I hope this helps! Let me know if you have any other questions.
