Which aspect distinguishes complementary from alternative medicine?

Rationale: A. Complementary medicine refers to therapies that are used in addition to conventional medical treatments to enhance overall care, reduce side effects, or improve quality of life. Examples include using acupuncture to help manage chemotherapy-related nausea, or meditation and yoga to reduce stress while undergoing standard medical treatment. The key distinction is that complementary therapies support but do not replace conventional medicine. B. Alternative medicine is not typically used alongside conventional treatments; instead, it is used in place of conventional medical care. This is what differentiates it from complementary medicine. For instance, a person may choose herbal remedies instead of prescription medications, which classifies as alternative rather than complementary therapy. C. Only alternative medicine is used in place of conventional treatments, not complementary medicine. Complementary approaches are additive, enhancing standard care rather than substituting for it. D. Both complementary and alternative medicine often emphasize the body’s natural healing abilities, such as using mind-body practices, herbal remedies, or holistic approaches to restore balance and promote wellness. Claiming that neither is based on natural healing is inaccurate.
