According to the document of the Belmont report, there are three basic elements that the informed consent should contain; these elements are information, comprehension, and voluntariness. The three elements are needed in order to analyze an informed consent. Therefore, the correct answer is D: information, comprehension, and voluntariness best describe the principle of informed consent as described in the Belmont Report.
The answer is:
"Last week I sent a tuner over to my parents’ apartment and had the piano reconditioned, for purely sentimental reasons.”
This is intrisic because she says, "purely for sentimental reasons" meaning she wasn't influenced by anything from the outside, this was something she did on her own based on how she personally felt. It was based on her emotions and her feelings. Hope this helps:)
