The correct answer is B. Harmonised System of Nomenclature.
The Harmonised System of Nomenclature (HSN) is an international system of names and numbers used to classify traded products. It was developed by the World Customs Organization (WCO) and is used by over 200 countries and territories. The HSN is based on a six-digit code, with each digit representing a different level of detail. The first two digits of the code identify the chapter of the HSN, the next two digits identify the heading, and the last two digits identify the subheading. The HSN is used to classify goods for customs purposes, such as determining the applicable tariff rate and other taxes. It is also used for statistical purposes, such as tracking the flow of goods in international trade.
