Final answer:
The WHO and the CDC are two groups that address health professionals, dealing with global and national public health issues respectively.
Step-by-step explanation:
The question addresses two distinct groups that cater to health professionals. Option A lists the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), both of which are involved in a variety of issues related to public health such as healthcare, insurance, employment, financial security, and consumer protection. The WHO is an international organization that provides leadership on global health matters, while the CDC is a national public health institute in the United States. These organizations focus on the broad health needs of populations and are not limited to the interests of specific professional groups. Therefore, these are the two groups that address health professionals.
