The correct answer is C. Respondent.

Primary data is data that is collected for the first time, specifically for the research project at hand. It is collected directly from the source, such as through surveys, interviews, or observation.

Books and newspapers are sources of secondary data. Secondary data is data that has already been collected and analyzed by someone else. It is often used to provide background information on a topic or to identify trends.

Reports are also sources of secondary data. They are often used to summarize the findings of a research study.

Respondents are the people who provide the data for a research study. They can be individuals, groups, or organizations.
