Show answer & explanation
Correct answer: C
In Entity-Relationship (E-R) diagrams, specific symbols represent different concepts:
(A) A double rectangle represents a Weak Entity Type. Thus, (A) matches with (II).
(B) An underlined oval or attribute represents a Key Attribute Type. Thus, (B) matches with (I).
(C) A double oval represents a Multivalue Attribute type. Thus, (C) matches with (IV).
(D) A double line connecting an entity to a relationship indicates Total Participation of Entity in a relation. Thus, (D) matches with (III).
Therefore, the correct matching is A-II, B-I, C-IV, D-III.
