Many people migrated from the North and East to the Sun Belt states during the 1950s because of the expansion of urban areas.

Explanation:

The Sun Belt is the region of the United States comprising the south and southwest of this country. This region showed great economic and demographic growth compared to the rust belt, a region that comprises the north and northeast of the United States.

For this reason, many people migrated from the North and East to the Sun Belt states during the 1950s.

The correct answer is C) the interstate highway system.

Many people migrated from the North and East to the Sun Belt states during the 1950s because of the interstate highway system.

When the US government built the interstate highway system in that decade, many Americans could travel to other places in a more fast and secure way. The sunny places or "Sun Belt" states are California, Florida, New Mexico, or even Texas. So people decided to leave the harsh weather conditions of the Northeastern states and moved to the mentioned states to have a better life. This action increased the population of the so-called Sun Belt states.
