Answer:
A. The proposal is approved, as it meets the ethical guidelines related to animal research
Step-by-step explanation:
Use process of elimination:
B. The proposal is approved, because while the animals suffer harm, the human participants suffer no psychological harm.
This can't be true because while the human participants suffer no psychological harm, there is no evidence that shows that animals suffer any harm in the experiment.
C. The proposal is denied, because the animal participants suffer physical harm.
Again, there are no animals that suffer physical harm.
D. The proposal is denied, because the animal participants cannot leave the study
There is no evidence that shows that animal participants cannot leave the study.
E. The proposal is denied, because the human participants are deceived
In what way could the human participants be decieved? This is not true.
By using process of elimination(and of course your psychology lesson) you will find that the answer is A.
...Plus, I also took the test and that's the answer. :)
