The answer is C. An object.
The sentence is incomplete because the subject (Calvin) sold (verb) something (it doesn't mention what), which is the verbal complement that is missing. In this case it is a direct object. The other options: A. A verb shows an action or state of being; B. A noun names something and D. The subject does or is something.
