language, lines, rhythm, and purpose
compressed meaning, purpose, and symbols

 The best — and correct — answer is:    [A]:

                  →  " style, language, rhythm, and rhyme. "

  →  {Note:  This is the best — and correct answer — based on the 4 [four] answer choices provided.}.

Note that some "timing" of sorts,  as a structural element of a poem —

          [in lieu of "rhyme" — if traditional "rhyme" is not used] — is often incorporated;  such as "meter" ; or "form".

For instance, Haiku poems consist of 3 (three) lines — in which:

         the first line has 5 (five) syllables;

         the second line has 7 (seven) syllables; and

         the third line has 5 (five) syllables.

Hope this helps!

       Wishing you the best in your academic endeavors
