Answer
A. Diathesis-stress
Explanation
The Diathesis-stress model suggests that each individual has certain biological predispositions (diathesis) and when they are paired with life stressors (stress) can cause a disorder. As Bruno's identical twin was diagnosed with schizophrenia, it may be inferred that Bruno also has a genetic disposition for schizophrenia. Therefore, the "Biological" answer seems plausible. However, Bruno himself didn’t show signs of the disorder until he joined an intense and stressful environment like the U.S. Army. This induction can equate to the 'stress' factor of the model. Either answer - "Diathesis-stress" or "Biological" has some ground. But due to the specific mention and display of environmental stress in Bruno's case, it leans more towards the "Diathesis-stress" model, hence, representing a more accurate answer. It clearly demonstrates an interaction of genetic or biological predispositions and environmental triggers, both contributing to the disorder.
