Answer:
The correct answer is B.
Step-by-step explanation:
The sunset is compared to a bruise which is usually the consequence of a painful encounter. Therefore, it immediately brings to mind a picture or memory of a painful encounter to the reader that was memorialised by a bruise as visible and vivid as a sunset. Furthermore, the comparison goes on to include "dark arteries" which is another painful experience as dark arteries are usually hardened arteries. They also block the adequate flow of blood which is a dangerous condition. And finally, the imagery closes with the mention of "a poisoned sky" which is another insinuation at danger as poison is a dangerous substance that often leads to a fatality.
