Step 1: Understanding the question.
The GI tag is given to products that have a specific geographical origin and possess qualities or a reputation due to that origin. These products are typically associated with a particular location.
Step 2: Analyzing the options.
(A) Production process: While the production process can be important, the GI tag is more closely related to the product's geographical origin.
(B) Raw material: Raw materials are part of the production, but the GI tag is primarily given based on location, not raw materials alone.
(C) Location: Correct — The GI tag is based on the geographical location, as products with GI status are often specific to a particular region.
(D) Occupation: Occupation is not a factor in determining GI tags.
Step 3: Conclusion.
The correct answer is (C) Location, as the GI tag is granted to products based on their specific geographical origin.
