Final answer:
A line of credit would be the most appropriate personal loan option for emergency funds, as it provides flexibility and lower interest rates.
Step-by-step explanation:
In the case of needing emergency funds, the most appropriate personal loan option would be a line of credit.
A line of credit allows you to borrow money up to a certain limit, and you only pay interest on the amount you borrow. It provides flexibility and can be used as a safety net for unexpected expenses.
On the other hand, payday loans should be avoided as they often come with high interest rates and short repayment terms, which can lead to a cycle of debt. Installment loans and deposit advances can also be used as emergency funds, but a line of credit offers more flexibility and usually has lower interest rates.
