Answer:
C.He is knowledgeable about nature.
Step-by-step explanation:
Caliban is the antagonist of the sage Prospero. He is described as a rude, wicked and ignorant savage who rebels against his master. Shakespeare's Caliban is not one-dimensional nor simple. It has a natural and wild power and its own right.
The excerpt exposed in the question shows a part of the confrontation between Prospero and Caliban is the most dramatic of all oppositions of the play. In this excerpt, when Caliban speaks "the fresh springs, brine-pits, barren place and fertile" shows that he is knowledgeable about nature.
