Answer:
C. open-ended.
Step-by-step explanation:
- Open-ended interviewing is a way of gathering information from people. An interviewer will ask participants questions, and who will answer those questions.
- Interviews are considered open-ended because, although questions can be scripted, interviewers generally do not know the content of the response. These interviews may have some questions for participants to gather basic factual data, such as age and gender, but they usually focus on participants' thoughts, feelings, experiences, knowledge, skills, thoughts and preferences.
so correct option is C. open-ended.
