Explanation:

- Gujarat is one of the leading producers of marine products in India due to its extensive coastline and thriving fishing industry.

- Punjab is not known for producing marine products because it is a landlocked state with no direct access to the sea.

- Maharashtra is another major producer, benefiting from its long coastline along the Arabian Sea.

- Kerala is renowned for its significant contribution to the marine sector, especially in seafood exports, thanks to its vast coastal area.

Option 2: Punjab is the correct answer, as it is the only option not associated with marine product production.
