1 1 vote It is asking about the "many-one relationship" of a weak entity set..It's not asking about the Weak Entity Set itselt.So the answer would be B if they ask about Weak Entity set itself.As they asked about the RELATIONSHIP, It's Diamon with double/bold border.So, Option A is the correct.TIPS : READ THE QUESTION VERY CAREFULLY.
