Option A is too specific, focusing on British settlements rather than the broader scope of European colonialism presented in the text.
Option B centers on indigenous displacement, which is not the passage's main subject.
Option C touches upon territorial expansion and political power but omits the crucial role of navigation technology.
Option D accurately captures the passage's core theme: 16th-century navigation advancements fundamentally altered colonialism. These improvements facilitated European settlement and political control across regions like the Americas, Australia, and parts of Africa and Asia.
Therefore, the correct choice is (D): 16th-century navigation technology advancements revolutionized colonialism, empowering Europeans to establish settlements and exert political authority over faraway territories.
