The answer is B: meeting society's expectations.
This novella by Tolstoy explores the metaphysical difference between an authentic life —that is, a life of sympathy and compassion— and artificial life —marked by mundane and vane self-interest and the fear of death.
What the passage in question shows, is that Ivan´s acquaintances are submerged in artificial life. Society´s expectations are, therefore, shown to be not more than mundane aspirations that reflect moral death in life.
