The correct answer is C. It is ineffective because it does not provide a logical reason for opposing the counterclaim.
Step-by-step explanation:
A claim is a statement that expresses the position of someone towards some situation or subject, in this case, this position is about just letting children play non-violent video games as the violent ones could have a negative influence. On the other hand, a counterclaim is an argument that aims at disproving or showing the main claim is not true, in this case, the counterclaim states there is not a link between violence in videogames and real violence which means the violence in videogames does not lead to violence in real life.
Additionally, a rebuttal is provided, which is an argument against the counterclaim by the author of the claim, similar to the counterclaim the rebuttal aims at disproving the opinion from the opposition and because of this the rebuttal should show there is a link between real violence and videogame violence or some other factor in videogames that leads to real violence. However, the rebuttal presented only mentions that allowing children to choose video games would empower them which is not related to the issue of violence discussed. Because of this, this rebuttal does not disprove the counterclaim or provide some logical reason to show the counterclaim is false and therefore is ineffective. Thus, it can be said the rebuttal is ineffective because it does not provide a logical reason for opposing the counterclaim.
