Question

Quizplus · Accepted Answer

The best choice is B because juvenile mice are known to have lower levels of serotonin, which is involved in regulating mood and aggression. Lower levels of serotonin can lead to increased aggression. The other options (A, C, and D) are less likely because they suggest that older mice or testosterone are the primary factors contributing to aggression, which is not always the case.
