if a borrower fails to repay a loan, what can the lender do?\noblige a relative to pay\nreceive federal…

Brief Explanations:

When a borrower defaults on a loan, if the loan was secured (with collateral), the lender can legally take the collateral as per the loan agreement. "Oblige a relative to pay" is incorrect as relatives aren't obligated unless they co - signed. "Receive federal financial support" is also incorrect as lenders don't get federal support for borrower defaults.

Answer:

C. seize the collateral (assuming the options are labeled A, B, C with A: oblige a relative to pay, B: receive federal financial support, C: seize the collateral)
