B. Developing

D. Poor

Answer 1

Hint: A developed nation refers to a sovereign state characterized by a developed economy, advanced technological infrastructure. A developed nation is identified by factors such as human development, GDP, industrialization, and freedom, and countries that have not yet developed in these categories are known as developing nations.

Complete answer:
In every society, providing service is an ongoing process of giving and receiving. When we look into the case of developed countries, we can see that a higher percentage of workers are employed in providing services as compared to less developed countries. The important activities that developed countries undertake are given as follows:
Tertiary Activities: Tertiary activity includes providing services rather than the production of tangible goods which means that they are not directly involved in the processing or the making of physical raw materials. The tertiary activity includes services provided by the work of a plumber, technician, barber, shopkeeper, driver, cashier, teacher, doctor, lawyer, etc. In the tertiary sector, employment has been increasing while it has remained constant or decreasing in the category of primary and secondary services.
Quaternary Activities: Quaternary activity refers to the sectors providing knowledge as a part of the economy. This sector includes knowledge-oriented economic activities such as the media, information technology, and research and development. This sector is run by big companies led by intensive research and capital investment and works along with other sectors of the economy.
Quinary Activities: Quinary activity constitutes an important part of the developed countries. These are services that focus on creating, re-arrangement, and interpretation of new and existing ideas and evaluating new technologies.
So, the correct answer is Option A

Note: A developed country has a post-industrial economy which signifies that the service or the tertiary sector becomes more important than the industrial sector. Some important developed countries include Norway, Switzerland, Australia, Singapore, Germany, etc.
