Why do people become violent according to proponents of biological theory?

• A. Violent behavior arises from random environmental events.
• B. They are born with a predisposition towards violence as a consequence of genetics.
• C. Violent behavior is solely a product of upbringing.
• D. Violence is a result of rational choice only.

Answer: (B)

Biological theory emphasizes that genetic and neurobiological factors can predispose someone to aggressive or violent behavior. Inherited differences in brain structure, neurotransmitter function, or hormonal regulation can influence traits like impulse control, emotional reactivity, and aggression. Because these tendencies can be present from birth and may be triggered or amplified by environmental experiences, some people are born with a genetic predisposition toward violence. That’s why the statement about being born with a genetic predisposition best fits this perspective.

The other ideas don’t fit as well: random environmental events don’t capture a genetic basis, upbringing alone ignores biological factors, and violence arising from rational choice implies decision-making independent of biology.
