Answer:
B) a paradox
Step-by-step explanation:
A paradox is a figure of speech which represents a logical statement and yet has contradictory remarks in it. The conclusion involves contradictory elements. The statement is contradictory but is true with logical reasoning. In line 16 of the poem, the paradox has been used to build the relationship between a boat and the sea. The boat is said to be 'longing' to go in the sea and at the same time, it is 'afraid' too.
