Even though option D is also related to Modernism and could be related to the excerpt, option C seems to be the correct one: It conveys the idea of isolation from modern life.
Modernist were called "the lost generation" because of their search for meaning among the fragments of modern life. In the excerpt, the words "lonely men" seem to address the theme of isolation and alienation in society. While everyone seems to have a role to perform in modern life, that does not mean they have found their true identity. Some sort of value seems to have been lost and, with it, men lost themselves. Modernism is characterized by the search of such value.
Type with your essay if you got one and type one paragraph with your intro and your 2nd with the mixed info and also 3rd as well and add some other detail and then your conclusion about it. I hope that is helpful.
