Answer:
C.
Step-by-step explanation:
Anecdotes can be defined as a form of a short story that is important and related to the imminent topic. This technique helps to add experience and personal knowledge about someone or something.
Consequently, when a writer of diary uses an anecdote in his/her writing, they try to represent any character. By adding anecdotes about a person will help the readers to understand that character more appropriately.
Therefore, option C is correct.
