一个介词的问题

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.

• Aonly if it would be taught as a separately required course
• Bonly if it is taught as a separate,required Course  
• Cif it is taught only as a course required separately  
• Dif it was taught only as a separate and required course  
• Eif it would only be taught as a required course,separately  
  

这个句子里面it会不会存在指代不明，既可以指代business ethics又可以指代business course

蟹黄蚕豆

不会啊，就近，ethics已经出现在第二句话中了。
