The correct answer is option a. "heredity".

Explanation:

Nowadays is still not clear the degree at which heredity and environmental factors affect social behaviors such as aggression.

Therefore, it could be assumed that Constance rejects environmental factors, while Agatha rejects heredity as the factor that affects aggression.
