What distinguishes the inhabitants of Lilliput from Gulliver?

The correct answer highlights the notable physical characteristic of the Lilliputians, who are only six inches tall. This distinctive trait significantly differentiates them from Gulliver, who is of normal human size. The extremity of their small stature contributes to the humor and satire in Jonathan Swift's narrative and emphasizes themes of perspective and the relativity of size and power.

The other options do not effectively capture the essence of what makes the Lilliputians unique in their interaction with Gulliver. While they might display intelligence or possess certain societal traits, their defining feature is their miniature size, which plays a crucial role in how they perceive and interact with the world around them, as well as how Gulliver navigates their society.
