A. bought it on credit

Explanation:

When you buy on margin, this means that you are borrowing money from a broker in order to purchase stock. This was a common practice during the 1920s. This allowed people to buy more stock than they would normally be able to. Most of the time, people who bought stock in this way were only required to put a small downpayment, often as small as 10%. This practice contributed to the Stock Market Crash of 1929.
