Explanation: Chilika Lake is a significant geographical feature located in the state of Odisha, India. It is the largest coastal lagoon in India and is known for its unique ecosystem and biodiversity. The lake is situated to the south of the Mahanadi River delta, which is the correct answer to the question.
To understand the context, it is important to know the geographical layout of Odisha and the location of major rivers in the region. The Mahanadi River is one of the major rivers in eastern India, flowing through the state of Odisha. The river forms a large delta before it meets the Bay of Bengal. Chilika Lake is located in this delta region, making it a part of the Mahanadi River system.
The other options provided in the question are rivers located in different parts of India and do not have any direct connection to Chilika Lake. The Kaveri River is located in the southern part of India, primarily in the states of Karnataka and Tamil Nadu. The Godavari River is located in central India, flowing through the states of Maharashtra, Telangana, and Andhra Pradesh. The Krishna River is also located in southern India, flowing through the states of Maharashtra, Karnataka, and Andhra Pradesh. None of these rivers are associated with Chilika Lake.
Chilika Lake is an important habitat for migratory birds and is known for its rich biodiversity. It is a brackish water lagoon, which means it contains a mixture of fresh and saltwater. The lake is connected to the Bay of Bengal through a narrow channel, which allows for the exchange of water and the mixing of salt and freshwater. This unique ecosystem supports a wide variety of flora and fauna, making it a significant natural resource and a popular destination for ecotourism.
In conclusion, Chilika Lake is located to the south of the Mahanadi River delta, making the Mahanadi River the correct answer to the question. Understanding the geographical layout of Odisha and the location of major rivers in the region is crucial for correctly identifying the delta associated with Chilika Lake.
