Answer:
A. One that cannot be answered with yes, no, or another single word.
Step-by-step explanation:
An open-ended question is a type of question that cannot be answered with a simple "yes" or "no" or another single word, and requires a more thoughtful and detailed response. These types of questions are often used in conversations, interviews, or surveys to encourage deeper and more nuanced discussions, and allow the respondent to provide more insight and information.
