The best answer would be C) Reference section because if I were to walk in a library (which I have) I don't see encyclopedias in the fiction section cuz encyclopedias are REAL not fake, and an encyclopedia is NOT a biography book, and its not fiction either so its in the reference section.
Encyclopedias usually would refer to other books for more information, and so they would be found in the "reference" section so that you can find books that are similar to the ones you want.
