Answer:
C. Interest Expense account is increased; the Interest Payable account is increased.
Step-by-step explanation:
A secured interest can be defined as a legal right granted by a borrower to a lender (creditor) over a collateral (the borrower's property) which permits or allow the lender to have a right to possess the property as soon as the lender defaults in making payment. The payment which is expected to be made by the borrower of a mortgage loan is considered a secured obligation because it is a lien or an enforceable legal claim.
When interest is accrued on a note payable, but not paid, the Interest Expense account is increased; the Interest Payable account is increased.
