The answer is D. not able to read or write.

To arrive at this answer, you can break down the word "illiterate" and analyze its prefix and root word. The prefix "il-" in English typically indicates the negation or opposite meaning of a word. In this case, the root word "literate" means to be able to read and write. So, by adding the prefix "il-" to the root word "literate," it indicates the opposite meaning, which is not being able to read or write. Therefore, the correct answer is D. not able to read or write.
