The correct answer is B) Novgorod.
The economy of the Republic of Novgorod included farming and animal husbandry. In addition, Iron was mined on the coast of the Gulf of Finland.
Other goods produced in the countryside, such as honey, wax fish, lard, flax and hop were sold in the market and exported to other Russian cities and foreign countries.
However, the richness of the city came from the trade of fur. It was a major place of trade between Russia and Europe thanks to being located near the Silk Road of China and the Baltic Trade Network.
