Answer: (A) is correct but (R) is wrong.

  • The assertion that rivers coming from northern mountains in the lower course tend to be slower is correct.
  • The rivers coming from northern mountains descend from a very high elevation and hence flow at a very high velocity.
  • Hence, the velocity decreases as the descent moderates and the gradient in slope is low. Therefore the low velocity is a consequence of the descent in slope.
  • On the other hand, the formation of a riverine island is an entirely different question which is a consequence of the speed of the river downstream not a reason or cause for it.
  • Therefore the answer is (A) is correct but (R) is wrong.
