_____ is the tendency for the presence of firearms to increase the likelihood of aggression,especially when people are frustrated.

A) The weapons effect
B) Displacement
C) The priming effect
D) Hostile aggression

The weapons effect is a phenomenon in which the mere presence of weapons, such as firearms, can increase aggression. Research has shown that people are more likely to act aggressively when they are exposed to firearms, especially in situations where they might feel frustrated or threatened. This effect is thought to occur because seeing a weapon can activate aggressive thoughts and impulses in the mind, making it easier for people to act on those impulses.
