Explanation:

John Donne's poem "A Valediction: Forbidding Mourning" is a metaphysical poem about the parting of two lovers. This farewell speech of the poet and his wife is a form of forbidding a person to be sad at the parting.

Lines 25 to 28 goes as follows-

If they be two, they are two so  

  As stiff twin compasses are two;  

Thy soul, the fixed foot, makes no show  

  To move, but doth, if the other do.

It is here that the speaker makes a comparison between him and his lover and the two feet/ legs of a compass. Thus, the correct answer is option C.

i think the answer is invented words, rhyming knack, alliteration, and, metaphor.
