The correct option is Punnamada Kayal.
Explanation
The Nehru Trophy Vallamkali (Boat Race) is a prestigious annual event held in the backwaters of Kerala. It features the traditional Chundan Vallams (Snake Boats) and takes place on the second Saturday of August every year.Detailed Analysis:
- Punnamada Kayal (Correct): The race is specifically conducted on the Punnamada Lake near Alappuzha (Alleppey). Although Punnamada is geographically a part of the larger Vembanad Lake system, the specific stretch where the race occurs is distinctively known as Punnamada Kayal.
- Vembanad Lake: This is the longest lake in India and the largest in Kerala. While Punnamada is an extension of Vembanad, in the context of the Nehru Trophy, the specific venue (Punnamada) is the most precise answer.
- Chilika Lake: Located in Odisha, this is the largest brackish water lagoon in India and is not associated with the Vallamkali boat races.
- Pulicat Lake: Situated on the border of Andhra Pradesh and Tamil Nadu, this is the second-largest brackish water lagoon in India.
Key Takeaway:
The Nehru Trophy Boat Race is held on the Punnamada Lake, which is the local name for the stretch of Vembanad Lake located in the Kuttanad region of Alappuzha.
