Answer:
Single seller is the correct answer.
Step-by-step explanation:
A market condition in which the goods available for sale are not in shortage which leads to the pricing power for the seller is known as sellers market.This term is generally applied to the property market when there are low supply and high demand. Excess demand for an asset shifts the balance of power to the seller's side in pricing. While in a buyer's market the situation is opposite and in it the supply is more than demand and hence the power is in buyer's hand for setting the price.
