Look at the relationships. All of them except B have them wrong. For instance "Movie ID -------------------- Borrower ID"

 

[nubix]

You'll need to familiarise yourself with relational databases. Once you get that, it's just logical.

The shop can have more than one copies of the same movie. The movie itself is unique, but the copies can be borrowed by different people. Similarly, each borrower is unique, but they can borrow more than one movie.

ie. one movie - many loans, one borrower - many loans.

-by Jesus, Matthew 7:7-8.... I think he was talking about spiritual things, not relational databases somehow..

Stupidly easy quesrtion, just choose the schema where the fields match.

It can't be A because Movie_Name goes to Movie_ID
It can't be C because Type goes to Phone
It can't be D because Movie_ID goes to Borrower_ID

But in B the field names match up. If you don't understand, give each field a colour, and select the schema where colours match. Braindead easy.
