b. Elementary school teachers

To determine the answer, we need to consider the educational qualifications required for each profession listed.

a. Preschool teachers typically require at least an associate’s degree in early childhood education, although some states or employers may require a bachelor’s degree. Therefore, option a is not the correct answer.

b. Elementary school teachers are responsible for teaching students in grades 1-6 and are required to have at least a bachelor’s degree in elementary education. Therefore, option b is the correct answer.

c. While a librarian specializing in early childhood education may have expertise in this area, the question specifically mentions the educational background required. To become a librarian, a master’s degree in library science is typically required, rather than a degree in education. Therefore, option c is not the correct answer.

d. Being a children’s book author does not necessarily require an education degree. Authors come from a wide range of educational backgrounds or none at all. Therefore, option d is not the correct answer.

In conclusion, the correct answer is b. Elementary school teachers as they require at least a bachelor’s degree in elementary education.
