Brahmaputra and Indus rivers are antecedent rivers. Which one of the f...
Antecedent drainage refers to a river that existed before the upliftment of the landmass that it flows through. In this context, Brahmaputra and Indus rivers are antecedent rivers because they existed before the Himalayan range came into existence.

Explanation of the options:

a) Which follows the initial slope of the Himalaya: This statement refers to a consequent river, which follows the initial slope of the landmass that it flows through.

b) Which existed before the Himalayan range came into existence: This statement is correct and defines antecedent rivers.

c) Which followed the dip or rock beds of the Himalaya: This statement is also correct and defines antecedent rivers. Antecedent rivers are able to maintain their courses through the rising landmass because they have already established their courses along the existing rock beds.

d) Which followed the strikes of rock beds of the Himalaya: This statement is incorrect as it is similar to option c.

Conclusion:

Antecedent rivers are a unique feature of the Himalayan region and are formed due to the tectonic activity and upliftment of the landmass. They are able to maintain their courses through the rising landmass by following the existing rock beds.
