choose the element of drama that classifies this scenario best.

diction
song
thought
character

The correct answer is:

Thought.

Thought is the element of drama that best classifies this scenario, because it refers to the theme of a play, what it means, the abstract issues and feelings that grow out of the dramatic action, as opposed to what happens in the plot.  Sometimes the theme can be explicitly stated in the title, or through dialogue by a character representing the playwright’s voice. It may also be less obvious and require some study.
