Career advancements in the health information technology industry are mainly based on A. education and credential(s). B. joining the American Health Information Management Association. C. dressing in a professional manner. D. knowing other people.
If the mean of question is at the level of America, I think "B" is correct, but in the level of world, maybe "A" more correct.
The word of "America" is not in the question but it is in second choose.
