Answer:
A) Cash Advance or C) Debit Card
Explanation: In Corporate Business, once company is sure about what is the budget amount, advance cash to vendors will be the most organized way to avoid out-of-budget erogations.
Why ? Because if in the budget were included all the expenses, and you paid in advance, you will safely rest the remaining period ( month/year ) as all expenses are covered, and no extra cash is expected. And, most important: suppliers owe you, as they must provide the good or service negotiated. Beside, paying in advance has the advantage to have prices fixed.
However, for personal use or small entrepreneurs, Debit Card could be the best option, as the maximum amount to be debited will be equal or less than to bank account balance. So, sum of payments is restricted. Corporations do not use Debit Cards for payments.
