Answer: Producers will either exit the market or produce less tangerines
Explanation:
If the marginal cost of producing tangerines is more than the price of producing them, it means that the supply of tangerines is quite high which is why the market reduced the price of tangerines.
The producers in the market will therefore act to reduce supply. They will do this by either reducing the number of producers so that the smaller number of producers will produce less or they will reduce production jointly in order to reduce supply. As this is a perfectly competitive market, the former scenario is more likely.
