The correct option is D do nothing to change the conditions they live in
Since people become monotonous with their life they accept it and it becomes very difficult to move on. From the first line in the passage we get a hint ‘..Most people lead the lives that circumstances have thrust upon them..’. People live a life dictated by their circumstances because they are not strong enough to change them, so option (d) is correct. Option (C) is a close one in this case but remember, the main point the author alludes to is the will of individuals and the lack of action they take. This sentiment is best reflected in option (d).
