According to the type of drawing and paying back, the loans are categorized as classical, revolving credits, bank overdraft, project loans, and syndication loans.

• With “classical” loans, after the drawing phase, the principal is paid gradually or by a single payment until a zero balance is achieved together with the interest for the period.
• With revolving credits, a limit of credit is set on the credit account of the borrower and both limits of credit and the due date are determined in a loan agreement. From concluding a loan contract till maturity date the borrower can draw the credit repeatedly within the limit.
• The bank overdraft is based on the same principle as the revolving loans, but the limit of the credit is set as a debit of a company’s current account. If the limit is overdrawn, the borrower pays a penalty interest rate. Loans are granted by financial institutions after a client presents an application form.
• The main medium and long term funding provided by banks are in the form of Project Finance. Project finance is the process of financing a specific economic unit that the sponsors create, in which creditors share much of the venture’s business risk and funding is obtained strictly for the project itself.
• Syndication loans are credits granted by a group of banks to a borrower. In a syndication loan, two or more banks agree jointly to make a loan to a borrower.

As can also be understood from the information given “the bank overdraft” is based on the same principle as “the revolving loans”, so the correct answer is B.
