Option 4 is the correct answer. The correct arrangement of the rivers from South to North is: Mahanadi, Cauvery, Krishna, Godavari.
To understand why, let`s consider each river:
- Mahanadi: It flows in the eastern part of India and is located towards the north.
- Cauvery: It is in the southern part of India and is located below the Mahanadi. So it flows south of the Mahanadi.
- Krishna: It is also in the southern part of India but located to the west of the Cauvery. Therefore, it flows north of the Cauvery.
- Godavari: It is in central India and flows further to the north of the Krishna.
Hence, the correct arrangement is Mahanadi, Cauvery, Krishna, Godavari.
