Answer:
Fourth Option
Step-by-step explanation:
Remember that diaries and autobiographies are books that are written by a person about that same person. So if that person is talking about a experience he/she had she is more likely to "include their opinions and feelings" or option four. If a person writes a story about him going to the park and then meets a stray dog and wants to keep it but his mother wouldn't let him. That person will write about how much he/she wanted the dog which makes you feel empathy for the writer which deeply affects the writing.
Hope this helps.
