The correct answer is B) Consumerism.
The 1920s innovations on the table showed a trend toward consumerism.
In the 1920s people felt optimism for the economic situation in the country. The possibility to get a credit increased the consumption of things that before were difficult to buy such as refrigerators, cars, radios, and washing machines. With that possibility, people wanted to spend money and to have more. So it is true that the 1920s innovations on the table showed a trend toward consumerism.
