The electrons will transfer to the foam cup and will remain in a concentrated, positively charged area on the cup where the rod was placed.

When the negatively charged rod touches the insulating foam cup, it will transfer some of its excess electrons to the foam cup. As a result, the cup will become negatively charged due to the increased number of electrons in it.
The correct response is:
The electrons will transfer to the foam cup and will remain in a concentrated, negatively charged area on the cup where the rod was placed.
