Final answer:
The violence-viewing effect is especially pronounced when the observed violence seems unjustified. The correct answer is option b.
Step-by-step explanation:
The effects of viewing violence can be further amplified when the violence seems unjustified, as it may create a stronger emotional response and trigger a negative behavioral reaction. Studies have shown that exposure to violent media content can lead to an increase in aggressive thoughts and behavior. For example, research has found a link between viewing violence and aggression seen in children. Therefore, option b. seems unjustified is the correct answer.
