The correct response is:
the maritime empires focused on control of the trade routes in the Indian Ocean rather than control of people and land.
This statement accurately reflects a key difference between maritime and land-based empires during the fifteenth and sixteenth centuries. Maritime empires, such as those established by Spain, Portugal, and later the Dutch and British, primarily sought to control trade routes and facilitate commerce across the seas, while land-based empires tended to exert direct control over vast territories and populations.
