This answer choice neither strengthens nor weakens the conclusion and, therefore, cannot logically complete the argument. The route students take to become qualified naturopathic healers doesn't directly support the argument's conclusion to encourage this form of medicine as a whole, as it does not point out a major benefit it has.

Great!

it comprises disciplines that are rooted in traditions from all over the world
natural treatments that prove themselves as successful cures can lead to the development of advanced medicines
it cannot be tested by the conventional methods of medical testing
plant ingredients are still used in many of the products we use daily
naturopathic students must perform many practice treatments before receiving their qualifications
