The correct answer is B and D.
B. Credit cards.
D. Personal loans.
Unsecured loans are not backed by collateral. Based on the financial history is how the lender decides if someone qualifies for a loan.
If someone defaults on unsecured loan then the lender can not take your property automatically.

The unsecured loan is not good because the APR is higher than the secured one reason being there is no assets which underlines for the creditor to stop if someone does not pay.
