Final answer:
The correct answer is B) The sample will include only one segment of frequent readers, as the book publisher's survey specifically targets library users, which is just one sector of the reading population.
Step-by-step explanation:
The question you're asking pertains to sampling methods used in statistics, which is a branch of mathematics. When a book publisher is planning a survey to learn more about reading habits based on a list of households who frequently use libraries to check out books, the sample described would be best represented by the option B) The sample will include only one segment of frequent readers. This is because the survey is targeting a specific group - those who use libraries often - rather than all readers or readers who read the most. Such a sample might not be representative of all reading habits since it doesn't include readers who buy books, borrow from friends, or consume digital content exclusively.
