Final answer:
Qualitative interviews involve gathering subjective information and insights from individuals. They can be unstructured, focus group, semi-structured interviews, but experimental debriefing interviews are not a type of qualitative interview.
Step-by-step explanation:
Qualitative interviews are a research technique used to gather subjective information and insights from individuals. They are commonly used in social sciences and other fields to explore people's experiences, opinions, and perceptions. The different types of qualitative interviews include unstructured, open-ended interviews; focus group interviews; experimental debriefing interviews; and semi-structured interviews.
Unstructured interviews are free-flowing and spontaneous, with no predetermined questions. Focus group interviews involve a group of participants discussing a specific topic. Experimental debriefing interviews are conducted after an experiment to gather participants' thoughts and reactions. Semi-structured interviews have a mix of predetermined questions and open-ended responses.
Therefore, the correct answer is c. Experimental debriefing interview, which is NOT a type of qualitative interview.
