Dakota is a nurse, Thai is a gynecologist, Reiko is a sonography technician, and Naomi is an embryologist. Which best compares the specialized training needed by these reproductive specialists?

Nurses such as Dakota generally need a professional license to practice. Embryologists such as Naomi may pursue professional certification, which recognizes specialized training but is different from a required license. A gynecologist also needs a medical license, so choices saying Thai only needs certification or that Reiko and Dakota only need certifications are not the best comparison.
