The primary source of data in the given options would be "Private organizations". Here's why:

1. Articles and newspapers: These are secondary sources of data. They usually contain information that has been interpreted, commented upon, or processed in such a way that it no longer represents the original observation or event.

2. Internet sites: These can be either primary or secondary sources, depending on the nature of the information. If the website is presenting original, firsthand information, it's a primary source. But if it's summarizing, interpreting, or analyzing information from other sources, it's a secondary source.

3. Private organizations: These can be primary sources of data because they often collect and generate data firsthand, through surveys, experiments, or observations. For example, a company might collect data on its customers' buying habits, or a non-profit might conduct a study on the impact of its services. This data is original and unprocessed, making it a primary source.
