Correct option is C
Explanation-
Myristica Swamps
This is unique wetland forest ecosystem, found only in the Western Ghats of India (mainly in Kerala, Karnataka, and Goa). It is named after the tree Myristica fatua, a wild relative of nutmeg. It is characterized by swampy waterlogged conditions, high biodiversity and ancient lineage of plant species. It is rare and endemic ecosystem – not found outside India.
Therefore, Myristica swamps are unique to India.
Incorrect Options -
Option a – Mangroves
Mangroves exist in coastal tropical regions worldwide (e.g., Southeast Asia, Africa, South America). India has important mangrove forests (e.g., Sundarbans), but they are not exclusive to India.
Option b – Cold Deserts
This is found in India (e.g., Ladakh, Spiti) but also in other parts of the world - Gobi Desert (Mongolia), antarctic Dry Valleys. So, not unique to India.
Option d – Riparian Forests
These forests grow along rivers and streams. This occurs globally across many ecosystems and continents. Again, not unique to India.
Final Answer: Myrstica Swamps (Option c)
