Explanation :
The option that is not a seafood fish of India is:

Surmai is a type of kingfish and is a seafood fish commonly found in Indian waters.
Udanmin appears to be a misspelling, and without clarification, it's not clear what specific fish it refers to.
Hilsa is a type of herring and is a well-known and widely consumed seafood fish in India.
Therefore, the correct answer to the question is (C) Echinoderms.
