The error is saying that the bid column with value cs02 does not exists in the Borrower table. If you look at the Borrows table again,

foreign key (bid) references Borrower(bid)

it clearly stated that the bid column should reference the bid in Borrower table. Hope that helps. If not, please ask.

Note: I'm assuming cs02 but it could be c201 in your case.

what is the problem?

This is the problem:

Msg 547, Level 16, State 0, Line 1
The INSERT statement conflicted with the FOREIGN KEY constraint "FK__Borrows__bid__3B75D760". The conflict occurred in database "databaselibrary", table "dbo.borrower", column 'bid'.

This mean that 1 of the bid does not exist in borrower data table.
