C is the correct answer, because if a written assignment is a 'humorous report', it means that it can be subjective, and that the author's personality is noticeable in the text. Whereas that is not the case in the other options.
While this should be something you should answer on your own with your own feelings, an example paragraph could be this:
Example: When I first learn to research things, I had difficulty citing and finding legitimate resources. Now, I've figured out how by asking for help and by using the skills I've been taught in the past. I've developed an understanding of how to reasearch by the lessons I've also been taught now. I've now developed the skills to see if an article or video is legitimate. I can now say I was happy to learn how to reasearch things properly, because it will benifit me in the future.
Hope that helps.
