Dr. Clairmont will have his psychology students training dogs from the local animal shelter to sit using various types of reinforcements. One group of students will train the dogs to sit by giving the dog a treat when it correctly performs. The other group of students will train the dogs to sit by firmly and loudly scolding the dog when it does not correctly perform. After 3 weeks of training, the dogs will be evaluated to see which group has more dogs that will sit on command. What might an ethics review committee decide about the proposal?
A-The proposal is approved, as it meets the ethical guidelines related to animal research.
B-The proposal is approved, because while the animals suffer harm, the human participants suffer no psychological harm.
C-The proposal is denied, because the animal participants suffer physical harm.
D-The proposal is denied, because the animal participants cannot leave the study.
E-The proposal is denied, because the human participants are deceived.

I know D,and E are incorrect. I'm stuck between A and B
