Answer: B - The retail sales industry is part of the tertiary sector of an economy. All economies are divided into sectors (education, real estate, health care, etc.) and those sectors can be categorized in four groups: primary, secondary, tertiary, and quaternary sectors. Primary sectors extract or harvest natural resources, such as mining or agriculture. Secondary sectors process natural resources into goods, such as manufacturing. Tertiary sectors are service sectors, such as retail sales and entertainment. Quaternary sectors are intellectual, such as education.
