Question

which of the following causes females to become more agitated and aggressive towar○ epinephrine○ amino acids○ pregnancy○ testosterone

Explanation:

Epinephrine is a stress hormone that triggers fight-or-flight responses, including agitation and increased arousal. Amino acids are building blocks of proteins with no direct link to this specific behavioral change. Pregnancy can cause mood shifts but not specifically targeted increased agitation/aggression as a primary effect. Testosterone is more strongly associated with aggressive behavior in males, and its role in female aggression is not the primary causal factor here compared to epinephrine's direct stress response.

Answer:

Epinephrine
