Answer & Solution
Answer: Option C
Solution:
The correct answer is Option C: Krishna
Let's understand why:
*
River Basin: A river basin is the area of land drained by a river and its tributaries (smaller streams that feed into it).
*
Peninsular India: This refers to the part of India that juts out into the Indian Ocean, south of the Indo-Gangetic Plain.
*
Highest River Basin: Here, "highest" doesn't mean the river itself is at the highest altitude. It means that among the major peninsular rivers, the Krishna river basin has the largest portion of its area at a higher average elevation than the other rivers mentioned.
Now let's look at the options:
*
A: Mahanadi: While a significant river, its basin isn't as elevated overall as the Krishna.
*
B: Godavari: The Godavari is a large river, but the Krishna basin has a greater portion at a higher elevation.
*
C: Krishna: The Krishna river basin has a considerable part located on the Deccan Plateau, which is at a relatively high elevation. This makes it the highest river basin among the options.
*
D: Narmada: The Narmada flows through a relatively lower elevation compared to Krishna's Deccan Plateau region.
Therefore, the Krishna river basin is considered the highest because a large part of its basin lies on the elevated Deccan Plateau.
