Which of the following is an example of an open-ended question?

An open-ended question is designed to encourage a more detailed response rather than a simple "yes" or "no." The chosen example, which in this case is "What features are important to you?", exemplifies this concept perfectly. It invites the respondent to elaborate on their preferences and share specific details regarding what they value, allowing for a broader discussion.

This type of question is particularly valuable in a customer service context as it fosters engagement and provides the customer with the opportunity to express their thoughts and needs comprehensively, which can lead to a better understanding of how to meet those needs effectively.

In contrast, the other examples are closed-ended questions; they typically limit responses to a specific choice or binary answer (e.g., yes/no or a selection between given options), which restricts the flow of information and discussion.
