A free root can stand alone with nothing added to it.
Given that it is 'free,' it can exist alone and doesn't have to have either prefixes or suffixes added to it in order to exist as a word. A root is the smallest part of a word (when you take off prefixes and suffixes) that still has a meaning.
For example: unbelievable - here, the root is believe, the prefix is un- and the suffix is -able.
Personally I would do: C and D.
They both give you a little information of what info will be covered in the book. If they have a lot of info of what you want to write about then they are keepers and if there is only a little info then you can still use them but if there isn't enough info to help you write a in-depth paper then ditch it or them and keep looking.
Hopefully this helped and good luck.
The answer is C. I took the quiz. Hope u get a 100%!
