Proceeding by elimination, the correct answer should be A: They include many points of view. A diary usually includes the point of view of the author only but in narrating events where other people are involved their points of view will be narrated by the author as well. Diaries certainly do not have a third person narrator and journals may or not have it depending on the type of article (news report, editorial) and the type of journalist (correspondent, interviewer, regular journalist). Diaries are not objective, they are the diary of a person and they reflect the person's point of view with a subjective bias. Journals should ideally be objective and they are supposed to but they are not always unbiased. Diaries certainly have a first person narrator and journals may or not have it depending on the type of article (news report, editorial) and the type of journalist (correspondent, interviewer, regular journalist).
