Answer : 4. "Karnataka"
Explanation :

Solution: Geographical Indication (GI) tag for cashew was recently given to Goa. This ensures that only cashew products from Goa can be labeled as “Goan Cashew”. The GI tag protects the authenticity of Goan cashews, helps consumers distinguish between authentic and imported cashews and prevents misleading labeling. This may help prevent nuts imported from Africa being sold as Goa cashews.
