……………………… is not a secondary source of information. A. Purchased outside source B. Internal company information C. Subjective estimation D. Government Agencies

To determine which option is not a secondary source of information, it's important to clarify what a secondary source is. A secondary source interprets or analyzes primary sources. Along these lines, let’s analyze each option:

1. Purchased outside source: This typically refers to information that has been collected and published by external entities, often based on original research. This is a secondary source.

2. Internal company information: This usually consists of data collected and generated within an organization, such as sales data, internal reports, or employee records. This is a primary source.

3. Subjective estimation: This reflects personal opinions or assessments rather than concrete data. It lacks the backing of original evidence and therefore does not fall under the category of secondary sources.

4. Government Agencies: While government agencies publish reports and data based on research, they can also be considered secondary sources, provided they are interpreting primary data within the context of their findings.

Based on this analysis, the option that is not a secondary source of information is:

Final Answer
