Final answer:
Roughly three out of every four HR professionals say they have been coerced into doing something morally or legally ambiguous at least once in their careers.
Step-by-step explanation:
The given question is related to the topic of ethics in the workplace, which falls under the subject of Social Studies. The question asks about the proportion of HR professionals who have been coerced into doing something morally or legally ambiguous at least once in their careers. To answer this question, we can refer to Milgram's study on obedience, where nearly 2/3 of the participants were willing to administer potentially lethal shocks to another person under the influence of an authority figure.
Using this information as a reference, we can infer that the answer to the question is three of every four (B). It suggests that roughly three out of every four HR professionals say they have been coerced into doing something morally or legally ambiguous at least once in their careers.
