While some academicians believe that business ethics should be integrated into every business course, others say that students will take ethics seriously only if it would be taught as a separately required course.
A. only if it would be taught as a separately required course B. only if it is taught as a separate, required course C. if it is taught only as a course required separately D. if it was taught only as a separate and required course E. if it would only be taught as a required course, separately
