The correct answer is: A. Transaction value.
The transaction value is the price actually paid or payable for the goods and services when sold for export to the country of importation, plus any costs, charges, or expenses incurred after the sale, such as commissions, packing costs, and insurance.
The MRP is the minimum price at which a product can be sold without incurring a loss. It is calculated by adding up the costs of production, marketing, and distribution, and then adding a profit margin.
The market value is the price at which a good or service is freely exchanged between willing buyers and sellers in the market. It is determined by supply and demand.
None of the above options are correct.
