Answer:
The correct option is : B) Securing a Certificate of Confidentiality
Explanation:
The Certificates of Confidentiality are issued by the National Institutes of Health and other Health and Human Service agencies. This certificate protects the privacy of the subject, by prohibiting the sensitive, identifiable information from getting disclosed forcefully. Therefore, the information can not be disclosed without the consent of the individual, to which it belongs.
Therefore, in the given example, Securing a Certificate of Confidentiality will help in keeping the individually identifiable information confidential.
