Identify elements of the short story on which a critic might comment

Plot

Duration

Theme

Character

Style

A critic's job is to express a reasoned opinion on any matter especially involving a judgment of its value, truth, beauty, or technique. Therefore, a critic might comment on all the alternatives in this question except for duration, which is applicable to movies, shows, plays, programs but not applicable to stories.

So the answer is these four elements:

Plot

Theme

Character

Style
