The correct answer is: **Electrons move from the rod to the wool.**
When the plastic rod is rubbed with wool, electrons are transferred from the rod to the wool. This process leaves the rod with a surplus of electrons, resulting in a negative charge on the rod, while the wool becomes positively charged due to the loss of electrons. Protons, which are located in the nucleus of atoms, do not move during this process.
