Answer:
A. Northern European economies are highly industrialized.
Step-by-step explanation:
Industrialization can be defined as a strategic process which typically involves the development of various industries in a country by the large-scale introduction of mechanized equipments and use of technology for the manufacturing of goods and services that meets the need or requirements of consumers.
Also, it involves the process of replacing human and animal power with an inanimate source of energy such as solar energy, steam plants, nuclear power, wind energy, etc.
This ultimately implies that, industrialization enhances or facilitates an increased level of output (production) in a country when it's adopted.
Since the Northern European economies are highly industrialized. Therefore, Northern Europe has become one of the world's most developed regions.
