Final answer:
The correct answer is option 4. In a market surplus, sellers will be frustrated by their inability to sell all their goods, leading them to decrease prices to attract more buyers and restore equilibrium.
Step-by-step explanation:
When there is a surplus in the market, it means that at the current price, the quantity supplied of a good or service exceeds the quantity demanded. This situation will frustrate sellers, as they are unable to sell all of their goods at the existing price.
As a result, sellers are likely to decrease the price to encourage more buyers to purchase their goods, and to reduce their excess inventory. This action helps move the market towards a new equilibrium where quantity demanded matches quantity supplied.
