which of the following?

In economics, all goods and services available to consumers are provided by "producers".

Explanation:

A manufacturer is one who produces products or services and delivers them. Producers integrate labor and capital— the so-called factor inputs— to produce something else — that is, to production.

Business companies are the key producers' sources and are generally what economists think when thinking about production. Farmers, suppliers and building firms are instances of the producers. They also have work opportunities for people who produce the goods or provide the facilities. Manufacturers comprise corporations, government, entities and others.
