The electrons will transfer to the cup and will remain in a concentrated, positively charged area on the cup where the rod was placed.
The electrons will transfer to the cup and will remain in a concentrated, positively charged area on the cup where the rod was placed.
The electrons will transfer from the cup to the metal can, causing both the cup and can to have a negative charge.

When the negatively charged rod touches the insulating foam cup, the excess electrons from the rod will transfer to the cup. Since the foam cup is an insulator, these electrons will remain in the cup rather than moving freely.
Thus, the correct response is:
The electrons will transfer to the cup and will remain in a concentrated, negatively charged area on the cup where the rod was placed.
