Final answer:
(C) Shegataro Morikubo's 1907 court case established the precedent that chiropractic is a distinct profession from osteopathy, solidifying its legal status and differentiating its practice and philosophy.
Step-by-step explanation:
The arrest and acquittal that established chiropractic as a distinct profession from osteopathy involved Shegataro Morikubo. In a pivotal court case in 1907, Shegataro Morikubo was charged with practicing osteopathy without a license.
The court's ruling declared that chiropractic, which Morikubo practiced, had a different philosophy and technique compared to osteopathy, solidifying the legal distinction between the two professions.
This precedent ensured that chiropractors could not be accused of practicing medicine or osteopathy without a license because of their unique chiropractic methods.
