Answer:
C). Research; Psychotherapy.
Explanation:
Informed consent is demonstrated as one of the most vital elements of research ethics or psychology that involve an elective agreement stating the research subject, its participants, and the potential risks involved in it. It provides the researchers with the necessary permission to conduct the research.
As per the question, informed consent concerning the 'research' could best be perceived as the one-time event but the informed-consent about a 'psychotherapy' would be taken as a continuing process as the therapists seek voluntary permission from their clients for distinct treatments and the risks as well as costs involved in it. Thus, option C is the correct answer.
