Answer:
The answer is: B) lost ownership of the stock.
Step-by-step explanation:
In the 1920s traders borrowed on margin to buy stocks. This means that they put a little amount of money to secure the buying of the stock and then borrowed the rest to complete the purchase. The problem with this was that if the price of the stock fell, the trader would lose all the money. On the other hand if the value rises, then the trader could make a lot of money. This was a very risky business practice.
