Answer:
Ivan Ilyich could recall pleasant days only in his childhood.
Step-by-step explanation:
From the given options:
* Ivan Ilyich couldn’t recall the days he spent as a child.
* Ivan Ilyich could recall pleasant days only in his childhood.
* Ivan Ilyich is thinking of someone’s pleasant childhood.
* Ivan Ilyich had a pleasant adult life but an unremarkable childhood.
Option B is the correct one since it uses the word ONLY and in the excerpt, he mentions that most of his memories are not as pleasant as they used to recall them or as they felt when he lived them, and he says "none of them EXCEPT the first recollections of childhood".
