Answer

Brief Explanations:

In the 1920s, a practice called "buying on margin" (using credit) became popular for stock - buying. People could borrow money to buy stocks, hoping the stock prices would rise so they could pay back the loan and make a profit. Cash was less common as a way to buy stocks during this speculative boom. Installments are more related to buying consumer goods, not stocks in this context. Speculation is the general activity, not the method of acquiring stocks. Buying on margin is a form of using credit.

A. credit.
