A criterion for waiving informed consent is that, when appropriate, subjects are provided additional pertinent information after the study. In which of the following studies would it NOT be appropriate to provide subjects with information about missing elements of consent:a. A study in which subjects were assigned to study activities based on an undesirable or unflattering physical characteristic as assessed by members of the research team.b. A study in which subjects were assigned to study activities based on an undesirable or unflattering physical characteristic as assessed by members of the research team. c. If subjects were to learn that the research team assigned them to study conditions based ond. A study in which subjects were told that they performed inthe third quartile on an anagram task when in reality students were randomly assigned scores that were not related to their actual performance.

b. A study in which subjects were assigned to study activities based on an undesirable or unflattering physical characteristic as assessed by members of the research team.

Explanation:

In case the subjects were used in the study judging by their unconventional, undesirable or unflattering looks and physical characteristics, it is better not to tell them the additional information after the study is concluded.

In that case, reveling the additional information can result in subjects being hurt, offended and angry, the reason for choosing them may seem unethical and wrong, and the researcher (and the study) could be put in the problem.

The subjects should not be harmed in the process and this study might cause them emotional harm.
