What does the term "uncanny" refer to?

The term "uncanny" refers to something that evokes a sense of unease or discomfort due to its strangeness or mysterious qualities. It often describes situations, events, or objects that are both familiar and yet unsettlingly different, creating a feeling of eeriness. This sense may arise from the unexpected nature of these occurrences, which can challenge our understanding of reality or the familiar.

For example, a perfectly lifelike mannequin might be considered uncanny because it resembles a human closely, yet the lack of life creates an unsettling contrast. The choice that conveys this strange and mysterious quality is the correct answer, as it aligns perfectly with the essence of the term "uncanny."
