Answer:
C. the use of a structure that may be characteristic of a genre
Step-by-step explanation:
When analyzing and comparing genres, one should focus on the characteristics of that certain genre. It should be seen in the system, structure, elements, and ways different genres use.
Authors that choose certain genres nearly always will adopt these elements in order to follow what is familiar to the readers of the genre, and their personal elements do not affect the analysis of the genre itself.
Therefore, in the analysis of the ways genres differently tackle the same subjects, we should focus on what is characteristic for them and compare the ways of the structure and elements.
