Detailed Solution & Explanation
Primary data refers to the data collected for the first time by the investigator or researcher themselves for a specific purpose. There are several direct methods to gather primary data from respondents, including the Interview Method (personal or telephonic conversation), the Observation Method (where the investigator systematically records behaviors or events without direct intervention), and the Questionnaire Method (where respondents answer a list of questions). If a researcher collects a sample of size directly from a population using any of these methods, the resulting data is primary. Since all of these are recognized methods of collecting primary data, they are all applicable.
Hence, **Option D** is the correct answer.
