The correct answer is D) development of a consumer advertising industry.

What took place in the United States in the 1920s was the development of a consumer advertising industry.

The famous "roaring 1920s" was a time of prosperity in the United States. People had cash and bouy things for their homes and other commodities. Advertising played a big role in marketing products that could be affordable for people, need it or not. This allowed consumerism to be part of American society in the "roaring 1920s."
