Answer:
The correct answer is B: whirlpool.
Explanation:
In Greek mythology, Charybdis represents a sea monster that appears in the form of a whirlpool. According to mythology, she lives under a small rock and drags ships underwater. Charybdis usually appears together with Scylla, another sea monster who lives under a large rock and tends to underwater ships with her.
In Odyssey, Charybdis is also described as a whirlpool who tries to swallow Odysseus' ship. He tried to avoid Charybdis, but, on the other side of a cliff, appeared Scylla. He chose to risk Scylla by accepting the risk to lose some members of its crew, rather than losing the whole ship by Charybdis.
