Humphreys collecting data for the tearoom trade study under the pretense that he was a lookout is an example of a violation of the principle of:
a. beneficence
b. respect for persons
c. justice

b. Respect for persons

Explanation:

According to my research on different research methodology, I can say that based on the information provided within the question Humphreys study was an example of a violation of the principle of respect for persons.

Therefore he violated the subjects trust and privacy by lying to them.
