The correct option is A 1929
In 1929, the US stock market exchange faced a huge crash when people began to sell their stocks after sensing a decline in the prices. Due to this, the stock prices fell by 33% between September and November of 1929. There was a decline in demand for goods, which led to a decline in production and shut down of factories. Eventually, people’s purchasing power began to reduce due goods becoming expensive. The cyclical effect of demand and price fluctuations caused massive unemployment.
