Question

sujay is conducting research on a group of factory machinists as part of a study on workplace stress and heart disease. before conducting his study, he explains the objective of the study to the subjects and tells them what they would need to do. he gives them the opportunity to choose if they want to participate or not. in other words, sujay is seeking ______. participant exclusion a placebo effect informed consent reinforcement

Explanation:

In research ethics, informed consent requires researchers to explain the study's objective and procedures to participants and let them voluntarily choose to participate. Sujay explains the study, tells subjects what to do, and gives them the choice to participate, which matches the definition of seeking informed consent. "Participant exclusion" is about removing participants, "a placebo effect" relates to treatment perception, and "reinforcement" is about behavior modification—none fit here.

Answer:

C. informed consent
