Final answer:
Neuroticism, a personality factor in the Five Factor Model that involves emotional instability and a higher propensity for negative emotions, is most associated with aggression.
The correct option is c.
Step-by-step explanation:
According to research on aggressive behavior, the personality factor that is most associated with aggressiveness is typically neuroticism. In the Five Factor Model of personality, neuroticism is described as an individual's tendency to experience negative emotions such as anger, anxiety, or depression.
Individuals who score high on neuroticism are often characterized as being easily upset or emotionally unstable, which can manifest in aggressive behaviors.
Neuroticism stands in contrast to the other Big Five personality factors: openness to experience (characterized by imagination and curiosity), conscientiousness (characterized by thoughtfulness and goal-directed behavior),
extroversion (characterized by sociability and assertiveness), and agreeableness (characterized by cooperativeness and trustworthiness). Of these, conscientiousness and agreeableness are typically inversely related to aggression, while openness and extroversion have less direct links to aggressive behavior.
Neuroticism is the end of the spectrum that involves emotional instability and a higher propensity for experiencing negative emotions, which are elements particularly linked to aggressive reactions to stressors.
The correct option is c.
