Which of these is the point of highest tension and drama in a narrative work?

The climax or turning point of a narrative work is its point of highest tension and drama, or it is the time when the action starts during which the solution is given. The climax of a story is a literary element.

The punch line of a joke is an analogy for the climax of a fictional narrative, though the absence of any falling action is an essential difference, which may reflect the nature of humor as opposed to the nature of drama.

In non-fictional narrative genres, even though the author does not have the same freedom to control the action and "plot" as in works of fiction, the selection of subject matter, degree of detail, and emphasis permit an author to create similar structures, i.e., to construct a dramatization.
