Step-by-step explanation:
The type of funding that occurs when a lender obtains funds from a line of credit at a commercial bank is Debt financing.
Debt financing involves borrowing money from a lender, such as a bank, and committing to scheduled interest payments, regardless of the firm's income. In this case, the lender provides funds through a line of credit, which allows the firm to access funds as needed.
For example, if a small business needs funds to cover operating expenses, it can obtain a line of credit from a commercial bank. The business can then draw funds from the line of credit whenever it requires additional capital.
