Answer:
C.
Step-by-step explanation:
Hello, and good evening, or morning for you, the purpose of the text is indeed to describe her family. It's not to recall past events ( mentions nothing of her past ) it's not to inform one's family ( there's only one family mentioned; hers ) and while it is introducing herself, it's introducing her entire family, not just her, therefore I do believe C. is the correct option.
