Professor Patty Is Very Distraught That Three Students in Her

Professor Patty is very distraught that three students in her class cannot afford to buy the 42-chapter book for the course. The book is used for two semesters, although not all students take the second semester. She finally tells the three students that she will make copies of the first 21 chapters for them, at no charge. Professor Patty makes the copies and gives each chapter to the students prior to her coverage of the relevant chapter in class. If Professor Patty is sued for copyright infringement:

A) she wins because the fair use doctrine permits use of the work for educational purposes.
B) she wins because she is not copying the entire book but only 21 chapters of it and is not making a profit.
C) she loses because by making and distributing the chapters, she is diminishing the value of the book on the national market.
D) she loses because she is copying whole sections and a significant portion of the book.
