Final answer:
The vocal cue from Ariel in the provided context hints at her longing for the human world, making the correct answer c) Castle.
Step-by-step explanation:
The vocal cue from Ariel in the context provided indicates a reference to a “strange new world above.” This line likely points to Ariel's longing or reference to the world above the sea, which in the narrative of The Little Mermaid represents both her curiosity and desire for a realm different than her own underwater existence.
This new world above strongly corresponds with the world of humans; therefore, options a) Ocean, b) Ship, and d) Mermaid would not constitute a “new” world to Ariel. Thus, by a process of elimination, the answer is c) Castle, which is part of the human world and would indeed be strange and new to a mermaid like Ariel.
