The correct option is D a quiet man who had intellectual interests
In the passage, we can note that Lin is thumbing through a book while everyone is working, he sits down on the grinding stone and flips through his Russian dictionary. At the beginning, he is seen flipping over a "dozen mildewed books", thinking to himself that Shuyu doesn't know how to care for books and that he should give them to his nephews. In this context, option B is the best answer. The other options are incorrect as they do not fit into the context of the passage.
