Which of the following qualifies as an open-ended question?

Open-ended questions are designed to elicit a wide variety of responses rather than a simple, restricted answer. By allowing respondents the freedom to express their thoughts and feelings in their own words, these questions foster deeper engagement and discussion. This characteristic is particularly useful in situations such as interviews, surveys, or customer feedback, where insights and qualitative data are valuable.

In this context, the choice that indicates questions which allow for a broad range of responses is indeed accurate. This approach encourages elaboration, facilitating a richer understanding of perspectives, opinions, and experiences. The other provided choices do not accurately define open-ended questions, as they either restrict responses or focus on formalities that do not align with the essence of open-ended inquiry.
