Concept:Collateral is a valuable asset, such as a house, that a borrower gives to a lender as security for a loan.
Explanation:When someone requests a loan from a bank or financial institution, the lender often demands an asset of value to protect the loan.
This asset, which may be a house, land, or vehicle, is held as security while the loan is being repaid.
If the borrower is unable to repay the loan, the lender has the legal right to seize and sell the asset to recover the money lost.
That asset is known as collateral.
Option A, "pledge," refers to a formal promise or commitment to provide the asset, not the asset itself.
Option B, "agreement," means a mutual arrangement between parties, which does not name the security item.
Option D, "surety," describes a person who guarantees another person’s loan repayment, not a property.
Therefore, "collateral" is the only word that correctly describes a house offered in exchange for a loan.
Answer:C. collateral
