The answer is D: "The speaker in "At the Tourist Centre in Boston" finds the display about Canada unreal."
The speaker in the poem refers to the display as a "dream", a "hallucination" and a "fiction". All three words refer to something that is not real. The speaker sees the depiction of her own country as something that does not reflect as she remembers her home.
Obviously if the speaker finds the depiction to be unreal, she cannot find it to be realistic (option A) as well. For something to be realistic and unreal would be contradictory.Furthermore, the speaker does not suggest any romantic (option B) feelings being evoked by the display. Finally, the speaker's words do not convey a sense of amusement (option C), even as she compares the display with her prior memories of Canada.
