Answer:
Medium of Exchange
Explanation:
A certificate of deposit represents a legal document issued by a commercial or economic institution such as a bank as evidence of a sum of money deposited by the individual for a particular period and with a specified rate of interest.
A Medium of Exchange, on the other hand, represents an intermediary system or instrument that can be used to make sales, purchases and facilitate the trade of goods or services between various parties. To qualify as a medium of exchange, the instrument should have a standard face value and must be acceptable to all parties.
Since Tara was able to put down $50,000 as represented on the Certificates of deposit, it becomes a medium of exchange, because it has a standard face value (as determined by the bank) and it is acceptable both by Tara and the estate from which Tara is purchasing the house.
