Step-by-step explanation:
The correct answer to the question of which of the following is NOT a reliable source of health information is b. All medical sites on the internet. While the World Health Organization (WHO), health care professionals, and health and medical journals are reputable sources of health information, the information available on the internet at large can vary widely in quality and accuracy.

A reliable source of health information should be trustworthy, accurate, and based on scientific evidence. From the given options, all medical sites on the internet are NOT a reliable source of health information.
Unlike reputable and credible sources, such as the World Health Organization (WHO), health care professionals, and health and medical journals, the information on the internet is not regulated for quality or accuracy.

Therefore, it is important to carefully evaluate the credibility and expertise of the sources when seeking health information online.
