Answer:
The correct answer is: Line of credit.
Step-by-step explanation:
A line of credit is an arrangement where a bank provides a maximum amount of loan the borrower can drop on at any time. The borrower who can be an individual, corporate, or government entity has as much flexibility as they want up to the maximum amount. Borrowers are charged interest only on the funds they draw and the rate of interest is often lower than that of a one-time loan.
