Final answer:
The ICA (International Chiropractors Association) prioritizes subluxation-based chiropractic with an emphasis on chiropractic philosophy, while the ACA (American Chiropractic Association) takes a broader approach.
Step-by-step explanation:
The organization that prioritizes subluxation-based chiropractic with an emphasis on chiropractic philosophy is the ICA (International Chiropractors Association). They believe that the nervous system plays a vital role in overall health, and that interference with the nervous system due to subluxations can lead to various health issues. They focus on adjusting and correcting subluxations to restore health and wellbeing.
The ACA (American Chiropractic Association), on the other hand, has a broader approach to chiropractic care and incorporates evidence-based practices alongside chiropractic philosophy. They place less emphasis on subluxations and more on providing evidence-based care for musculoskeletal conditions and promoting collaboration with other healthcare professions.
So, the correct answer is A. I only.
