It should be Denotation because Denotation is the literal meaning of the word; Connotation is the figurative meaning of it, or the feelings or idea that's invoked by the word, in this case, <em>slam. </em>So the Connotation of the word <em>slam </em>could be "angry, frustrated, argument," because that's what you think of when you see the word <em>slam </em>used in whatever context it is (Think: in what scenario would you use the word <em>slam </em>for the story you're telling?). On the other hand, Denotation is the definition of the word that you would normally expect to see in the dictionary.
