Correct Answer: Option A) 1 only
All rivers in Kerala originate from the Western Ghats - True
Most rivers in Kerala do originate from the Western Ghats, which form the eastern boundary of the state. The Western Ghats are the primary source of all major rivers in Kerala including Periyar, Bharathapuzha, Pamba, Chaliyar, etc.
The Karamana and Neyyar rivers flow eastward - False
This statement is incorrect. Both Karamana and Neyyar rivers flow westward, not eastward. Almost all rivers in Kerala flow westward from the Western Ghats into the Arabian Sea. Kerala's geography is such that rivers originate in the elevated Western Ghats in the east and flow downward toward the west where they meet the Arabian Sea.
The Bharathapuzha river flows through the Wayanad Plateau - False
Bharathapuzha, also known as Nila, doesn't flow through the Wayanad Plateau. Bharathapuzha primarily flows through Palakkad, Malappuram, and Thrissur districts. The rivers that flow through Wayanad include Kabani (a tributary of Cauvery) and Chaliyar.
