The answer is: A. He is extremely worried about his health.
In the excerpt from Leo Tolstoy’s "The Death of Ivan Ilyich," after having a serious conversation with his doctor, who refuses to answer further questions, Ivan undergoes an intense state of anxiety or uncertainty over his potential health problem. On the way home, he is so concerned about what condition he might have that he tries to examine the doctor's words, observes that everything he perceives on the road has a somber feeling, and his body pain becomes more severe.
