    Hi, Great Explanation. I understand a lot from your other videos too.
    Here are the unclarified things I found in this video. May be I'm wrong or you missed it unfortunately.
    Please Clarify it.
    1) Option 8B: You didn't mention Total participation is necessary.
    2) Option 8C: You didn't include Type(or Discriminating) attribute in relation.
    Thank you.
