The correct answer is C) conurbanization.

When studying the Calumet region of Illinois and Indiana, Alfred Meyer noted four stages of development as new groups occupied this land. In stage 4, conurbanization, new cities spread across the new territory and grew toward one another.

When a group of cities grows across the land, they get to the phase conurbanization, coined by Alfred Meyer. These cities once were separated but intense urbanization made them grow to the point of joining one another, creating a much bigger metropolitan area. Once separated by the country or natural areas, these cities now are part of each other, as is the case in many areas in the United States or large cities in England, Mexico or China.
