Answer:
d. broken jaw
Explanation:
Metaphor is a figure of language that consists in the use of a word or expression with the sense of another with which it is possible to establish a relation of similarity.
In "The Hollow Men" by T.S. Eliot, the metaphor compares the valley of hollow men with a broken jaw, to convey a sense of discomfort to the reader, and to show that the valley of hollow men is not a pleasant place.
The part of the poem where this comparison happens is:
"The eyes are not here
Here the eyes do not shine
In this valley of tibial stars
In this helpless valley
This broken jaw of our lost kingdoms."
