The correct answer is: 2 to 9
To find the ratio of nonfiction novels to all novels, we need to add up the number of nonfiction novels and divide it by the total number of novels.
The number of nonfiction novels is 2, and the total number of novels is 2 + 4 + 5 = 11.
Therefore, the ratio of nonfiction novels to all novels is 2:11.
