Answer:
A.) The visit to the garden contrasts with the internal turmoil the speaker is experiencing.
Step-by-step explanation:
"Absence" by Elizabeth Jennings features a speaker who lost someone he loved very much. The poem does not show whether the loved one died, or left, but we know that the speaker is no longer with someone he loved so much and this separation completely changed what he is inside, causing him to change his mind, concepts, thoughts and views of the world. The speaker is no longer the same person, but when he visits the garden where he saw the person he loved the last time, he was annoyed because the garden was still the same, but his interior was completely modified.
In other words, we can see that the visit to the garden contrasts with the internal trubulence that the speaker is feeling, because unlike him, the garden remains the same.
