Final answer:
The answer to the multiple-choice question on aggression is option B: hostile; instrumental. Hostile aggression is motivated by anger and intent to harm, while instrumental aggression serves a specific goal.
Step-by-step explanation:
When aggression stems from feelings of anger, it is called hostile aggression. When it is a means to achieve some goal, it is called instrumental aggression. Therefore, the correct answer to the multiple-choice question is option B: hostile; instrumental. Hostile aggression is driven by emotions and the intent is to cause pain or harm. An example of hostile aggression could be a physical altercation due to rage. On the other hand, instrumental aggression is more strategic, aiming at a certain objective without necessarily intending to inflict pain.
