The correct answer is C. Supplier of goods located in Goa and place of supply of goods in Goa.
An intrastate supply is a supply of goods or services that takes place within a single state. In this case, the supplier is located in Goa and the place of supply is also in Goa. Therefore, this is an intrastate supply.
Option A is not an intrastate supply because the place of supply is in a different state (Mumbai). Option B is not an intrastate supply because the supplier and the place of supply are in different states. Option D is not an option because only one of the options is correct.
