Answer:
B. a sense of temptation and danger
Step-by-step explanation:
Temptation is achieved by saying that the waves "curled up" to the character's feet. This sounds as if the character got tempted by the sea; the " foamy" little waves sounds as if they were inviting her to walk into the sea. Then, the danger of the situation is expressed through the picture of a serpent coiling around the charater's very same feet. The sea sounds tricky : it invites the character to walk in but if she did, she would never be able to walk out.
