The correct option is "c.banking"
In the modern sense of the term, banking had its beginnings in the rich cities of northern Italy, such as Florence, Venice and Genoa, at the end of the medieval period and the beginning of the Renaissance. The Bardi and Peruzzi families dominated banking in 14th century Florence and established branches in many other parts of Europe, perhaps the most famous Italian bank was the Medici, founded by Juan de 'Medici.
