Answer:
The bond is unsecured, doesn't have right to collateral, is called debenture.
Step-by-step explanation:
The security in this question has a maturity date with stated interest, While, both preferred stocks and bonds would have a guaranteed payment, stocks are ownership in a company and wouldn´t have maturity date, so it can't be a stock.
Maturity dates are relevant to bonds, loans to a company, because that is the date when the bondholder should receive final payment on the face value of the bond. In this case 1.000.
