The correct option is C Eclectic
In lines 30-39 of the passage the author imagines a school system where the students reads books together and also have a separate reading life of their own and in college, they continue to be assigned certain books but more important than this would be those books that students would come across on their own- in libraries, bookstores or at a friend's place- and with each book they would come to know more of history, different languages and cultures. In this context, we can deduce that in lines 30-39, the author presents a model of education where students explore the world through wide- ranging reading. This type of education system can best be described as all-inclusive or eclectic. Thus C is the best answer. The other options are incorrect because they do not fit the context
