The answer is A i read the text and A sounds like a reasonable answer
In Chinua Achebe's short story, Marriage is A Private Affair, the lead character, Nnaemeka wants to marry Nene, the girl that he loves, but his father wants him to marry to the girl that he has chosen for his son. It is the beginning of the conflict between the father and son and also between the traditional and modern values which runs throughout the story. Therefore, Nnaemeka is unsure what will his father say, how will he react after learning that he is going to marry the girl that he himself has chosen.
My personal recommendations would be to
A ) Make the subject shorter, like "Reason for Absence" or "My Absence"
B ) Make the email more formal. (You don't have to copy my recommendation word for word but if you want to or use it for reference that works):
"Good Morning/Afternoon/Evening Mrs. __,
I hole you're have a lovely morning/afternoon/evening. Today I was absent and I apologize for the inconvenience. The class meeting didn't appear on my canvas courses and I couldn't find a zoom link. If there's anywhere I can find either one for the future please let me know and again I'm sorry for the inconvenience.
Sincerely,
__"
