The appropriate response is A. The French pioneer realm constituted the abroad settlements, protectorates and command domains that went under French control from the sixteenth century ahead. A refinement is by and large made between the "primary pilgrim realm", that existed until 1814, by which time the vast majority of it had been lost, and the "second pioneer domain", which started with the victory of Algiers in 1830. I guess you answered you own question though lol.
