What formed the basis of russia’s economy in the early 1900s?
a. farming
b. steel
c. mining
d. textiles

The best and most correct answer among the choices provided by the question is the first choice "farming"

During the early 19th century Russia developed trade relationships with other European countries and exported large amounts of grain. But most of the export revenue that flowed into the empire simply lined the pockets of aristocrats and powerful land-owners; it was not used as capital to develop an industrialised economy.
