The answer is B

Google "primary data collection" and read carefully.

The primary data collection method that is not listed is "secondary research."

To determine which one of these is not a primary data collection method, we need to understand what primary data collection involves and then evaluate each option accordingly.

Primary data collection refers to the process of gathering information directly from original sources or firsthand experiences. The data collected is specific and tailored to the researcher's needs.

Now, let's evaluate each option:

1. Questionnaire: This is a common primary data collection method. Researchers design a set of questions that participants answer either in writing or verbally to obtain the desired information. It directly gathers data from individuals.

2. Customer feedback: This is also a primary data collection method. Researchers gather feedback directly from customers, which can be collected through surveys, comment boxes, online reviews, or direct conversations.

3. Observation: Observation is yet another primary data collection method. Researchers observe and record behaviors, events, or phenomena in their natural environment to gather data. It involves systematically watching and noting details without interfering or influencing what is being observed.

4. Interview: An interview is also a primary data collection method. Researchers conduct one-on-one or group interviews to obtain information directly from individuals or experts. Interviews can be structured (following a prepared set of questions) or unstructured (more conversational and flexible).

Therefore, based on this evaluation, all of the options mentioned—questionnaire, customer feedback, observation, and interview—are primary data collection methods. None of them can be identified as not being a primary data collection method.
