Step 1: Understanding the Question:
The question requires identifying the geographical error in matching major Indian estuarine/lagoon systems to their respective states.
Step 2: Detailed Explanation:
• Mandovi-Zuari System (Option B): The Mandovi and Zuari are the two primary rivers of Goa, not Karnataka. Their estuarine system is vital for Goa's inland fisheries and maritime trade (Mormugao port). This is the incorrectly matched pair.
• Hooghly-Matlah (Option A): This is the largest estuarine system in India, part of the Ganga-Brahmaputra delta, and is located in West Bengal. It is world-renowned for its Hilsa and prawn fisheries.
• Vembanad Lake (Option C): The largest lake/estuarine backwater system in India, located in Kerala. It is famous for its Nehru Trophy boat race and the "Karimeen" (Pearl spot) fishery.
• Chilka Lake (Option D): Asia's largest brackish water lagoon, located in Odisha. It is a major biodiversity hotspot and a critical source of income for local fishers.
Step 3: Final Answer:
The incorrectly matched pair is Mandovi-Zuari estuarine system – Karnataka (it should be Goa).
