By building military bases around the world, imperialist nations mainly aimed to resupply naval vessels. protect far-flung colonies. initiate wars in several places at once. avoid warfare within their own nation.

The right answer is protect far-flung colonies.

Military installations dispersed throughout the world from large bases that are true cities, to radar and telecommunications stations, are used for protection purposes. Those regions where the bases are located have become one of the important stages of the worldwide struggle for power, which obviously includes the dispute over strategic resources.
