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" answer, allowing individuals to express their thoughts, feelings, and experiences more fully.

The example "What features are important to you?" exemplifies this because it prompts the respondent to elaborate on their preferences and priorities in a way that reflects their personal opinions. This type of question encourages dialogue and provides insights into the customer's needs, which can lead to a better understanding of how to assist them.

Other options are more closed in nature. They typically lead the respondent toward a limited range of responses, restricting the information that can be gathered. For instance, "Is this all for you today?" and "Do you like blue or brown?" are straightforward questions that can be answered with a simple affirmation, negation, or choice between two options. Meanwhile, "Can I help you?" also prompts a brief response, which does not invite the same level of engagement or detail.
