Answer:
B
Step-by-step explanation:
The production of goods and services is known as an industry, which can be divided into three types: primary, secondary, and tertiary.
Primary industry, which generates raw materials, includes agriculture, forestry, fishing, and mineral extraction. Secondary industry, also known as manufacturing, processes raw materials into products. The tertiary industry is the provision of services, including food, transportation, education, and financial services.6 The most basic tertiary industry is commerce (trade in goods), which encompasses everything from local shops to international shipping companies.
Throughout most of history, economies were based mainly on agriculture, manufacturing (by hand), and commerce. Though the latter two thrived as important sectors of many pre-modern states, neither came to dominate a national economy until the Industrial Revolution, when manufacturing by hand was largely superseded by machines (allowing manufacturing to become the dominant sector of industrialized states). Eventually, manufacturing was in turn succeeded by the tertiary industry as the largest component of the world's most advanced economies.
