Answer: I would contend that the right answer is the C) Conceit.
Explanation: Just to elaborate a little on the answer, it can be added that by comparing his soul and that of his lover to two fixed compasses, the speaker in this poem is using a conceit, which is a figure of speech that establishes a witty comparison between two differing things or situations—much like a simile or a metaphor. As a metaphysical poet, John Donne (1572-1631) often made brilliant and ingenious comparisons or established analogies between physical objects and inmaterial or spiritual things, such as the compasses and the souls in this stanza. This is called a metaphysical conceit. Two souls are like two stiff compasses, which only move in unison—if one moves then the other moves too.
