The correct option is C
The Military Revolution is a historiographical concept that designates the radical change in the organization, strategy and armament of the European armies during the Modern Age and its consequences at a political, social and economic level. The term was introduced by the historian Michael Roberts in the 1950s. Roberts linked the changes in European methods of war promoted by the incorporation of new military technology with broader historical processes. In this way, he argued that innovations in tactics, instruction and doctrines by the Dutch and Swedes between 1560 and 1660, which maximized the use of firearms, led to greater professionalization of the army.
