HELP !!!!!!!!!! I am pretty sure the answer is not 1 and 3, because I took it 6 times and it all comes back telling me the question on customer and vendor workflow is incorrect. Can someone confirm the answer for this question?

Question 9 Based on the relationship and agreement with the vendors, what are the 2 vendor workflow options to pay your vendors? Bill > Pay Bills Invoice > Receive Payment > Create Deposit Create Purchase Order Expense or Check Delayed Charge > Pay Bills
