The root words from your list are:
- cred (from the Latin "credere," meaning "to believe")
- graph (from the Greek "graphē," meaning "writing" or "to write")
- vis (from the Latin "videre," meaning "to see")
The other options, "anti" (a prefix meaning "against"), and "con" (a prefix meaning "with" or "together"), are not root words but rather prefixes.
