Detailed Solution & Explanation
Data can be classified as either primary or secondary depending on its origin. Primary data refers to original statistical data collected for the first time by an investigator or researcher for a specific inquiry. Secondary data refers to data that has already been collected, compiled, and published or stored by some other agency or person. Government records (Option A), research articles (Option B), and journals (Option C) are all pre-existing, compiled, and published sources, which makes them secondary data. On the other hand, questionnaires filled by enumerators (Option D) involve fresh, first-hand data collection directly from respondents in the field for the study at hand, making it a source of primary data.
Hence, **Option D** is the correct answer.
