Answer:
B) Only a few buyers or peaches
Explanation:
A market with many peach suppliers, but only a few buyers, is an Oligopsony, from the Greek oligoi "few", and opsonia "purchase".
In this type of market, the few peach buyers have great power over the suppliers. They can influence prices directly by choosing to buy the cheapest peaches, and they can also influence quality, delivery times, and convenience. Peach suppliers would have it almost impossiblet to collude under these conditions.
