"O my Hiawatha! Is there anything can harm you?
Anything you are afraid of?"
But the wary Hiawatha
Paused awhile, as if uncertain,
Held his peace, as if resolving,
And then answered, "There is nothing,
Nothing but the bulrush yonder,
Nothing but the great Apukwa!"
And as Mudjekeewis, rising,
Stretched his hand to pluck the bulrush,
Hiawatha cried in terror,
Cried in well-dissembled terror,
"Kago! kago! do not touch it!"
"Ah, kaween!" said Mudjekeewis,
"No indeed, I will not touch it!"

Which inference is most clearly justified by these lines?
A. Hiawatha is afraid of the bulrush.
B. Hiawatha is trying to trick Mudjekeewis.
C. Bulrushes were thought to be poisonous.
D. Mudjekeewis is planning to attack Hiawatha.
