The expression "in question" is used to talk about a specific thing or person that is being referred to in a discussion or conversation. It means that the thing or person being talked about is the main focus of the conversation. For example, if someone says "The book in question is very interesting", they are referring to a specific book that is being discussed and considered important at that moment. So, when we use the expression "in question", we usually use it to emphasize that something is the center of attention or discussion.
