Which of these statements is true of both journals and diaries?
a. they are objective.
b. they have a third-person narrator.
c. they include many points of view
d. they have a first-person narrator

Let's take a diary first. It's subjective, not objective, so option a is wrong. It's from first,not third-person perspective, so b is wrong too. It does not include many points of view either, so C. Is not correct. D. Is correct both for both diary and journal (note that "journal" has many meetings. )

To sum it up you’ll get in a lot of trouble and even some legal action can be taken
