Answer:
D
Explanation:
It is most certainly not C or B so that leaves A and D. Usually, in herd situations peer pressure is present, especially in decision making except the derivative from this would be the motivation aka emotion. The brain isn't fully developed and when around peer's or a large group one is more likely to make hasty and emotional instead of logical decisions hence why I think the answer is D. Hope this helps... sorry if i'm wrong :)))
