Answer:
A.) Collateral.
If you get a loan from a bank or get bailed out of jail you will eventually have to pay the loan/bail back to the bank/bail bondsman so you can stay out of jail. Or you can take another route, You can put up your property as Collateral, So if you dont pay your Loan/Bond they can take your property and sell it to a Auction/LandOwners so they get the cash they used to bail you out back.
