Which of the following is associated with Chilika lake?
I. First Indian wetland under the Ramsar Convention.
II. Irrawaddy dolphins
III. Lacustrine plain
Select the correct answer using the code given below:

The Correct answer is Option 1. 

Key Points

• First Indian Wetland under the Ramsar Convention (I): Chilika Lake was designated as the first Indian wetland under the Ramsar Convention in 1981. Hence Correct.
• Irrawaddy Dolphins (II): Chilika Lake is home to the Irrawaddy dolphin, a species that is found in this lake and is known for its unique characteristics. Hence Correct. 
• Lacustrine Plain (III): A lacustrine plain refers to the flat areas formed by the sedimentation processes in lakes. While Chilika Lake is a significant wetland, it does not specifically characterize the surrounding area as a lacustrine plain. Hence not correct. 
• Therefore, the correct answer is Option 1: I and II only.
