Answer:
b. A shorter treatment time than conventional medical care
Explanation:
Complementary and alternative medicine (CAM) can be products or practices given to patients which are not a part of standard medicine, for example: acupuncture, guided imagery, and drinking green tea.
Heather is CAM practitioner for treatment of a chronic illness, so he can expect a short period of conventional medical care that can include physical and mental health practices which do not include harsh medications for treatment of a chronic illness.
Hence, the correct answer is "b. A shorter treatment time than conventional medical care".
