The correct answer is D. Text structure and style.

Explanation:

In writing, the text structure refers to the way the contents in a text are organized and whether the text develops the main ideas by providing the information required through details, supporting statements or evidence. Additionally, the text structure delts with the division of the text itself (introduction, development, and conclusion) and the organization of contents and ideas on it. On the other hand,  the style refers to the author's technique for developing the ideas in a text including the use of syntax, the election of words or diction and the tone or attitude of the author towards the topic he or she is writing about. Also, the style varies in each text and according to each author. The previous ideas imply for evaluating the text structure it is necessary to analyze the organization of contents and ideas, and for evaluating the style one should consider the tone (attitude of the author and word choice or diction). Thus, organization, tone and word choice should be considered when evaluation text structure and style.
