Answer:
The correct answer is 4. Hoarding
Step-by-step explanation:
A practice that consists of retaining or buying goods in large quantities before they reach the consumer market, in order to sell them when their prices are higher than the current ones. The hoarding is based, therefore, on the forecast of an increase in demand and is a speculative practice that in general can be considered normal: the one who monopolizes runs the risk of making mistakes in his forecasts and losing part of the assets that he has committed to the purchase, therefore resulting in a plaintiff like any other who attends the market; When done in very large volumes, however, it is considered a monopolistic practice that many countries sanction in various ways.
