Final answer:
The maximum total points for creating a post on a forum based on the grading rubric is 20 points. This assumes that the post meets all the length and content requirements, with no points specified for simply viewing the forum.answer is option D.
Step-by-step explanation:
The points for creating a post and viewing the current week's forum are based on the grading rubric provided. According to the rubric, an initial post is worth up to 20 points if it meets both length and content requirements. However, there is no mention of specific points just for viewing a post. Assuming that the standard engagement, which includes viewing and creating a forum post, is in question, we will consider the points awarded for the initial post creation.
For a comprehensive forum contribution, if one makes an effort that is considered as meeting length and content standards, one could earn 20 points. If the initial post needs improvements, the points could range from 15 to 5 points, depending on the degree of effort. No points are awarded if the initial post is not made. Since there is no explicit mention of points for viewing, the total points possible for creating a post would be 20 points at most.
