Final answer:
The speaker anticipates that the chronic disease, a symbolic representation of an internal struggle, will affect them for their entire life, making option C the best description of their experience.
Step-by-step explanation:
From the passage, it is evident that the speaker is describing their experience with a chronic and incurable condition, which is intensely personal and emotionally charged. The disease, while not physical, symbolizes a deep-seated emotional or psychological distress that affects individuals throughout their lives. The best answer to the student's question is C) The speaker anticipates a lifelong struggle with the recurring disease.
This is because the speaker describes the condition as one that "has recurred in me and does and will continue until the day I die." Therefore, the disease is not seen as a temporary or external issue but rather as an intrinsic and persistent struggle.
