Electrons will always move toward the more __________ charge.

Electrons are negatively charged particles, and they are attracted to positively charged objects. This fundamental principle of electricity is rooted in the behavior of electric charges: opposite charges attract, while like charges repel. Therefore, when an area has a positive charge, it creates an electric field that exerts a force on nearby electrons, pulling them toward the positively charged region.

In contrast, areas that are neutral or negatively charged do not exert this attractive force on electrons to the same degree. Neutral areas have no net charge to attract or repel electrons, while negatively charged areas would actually repel electrons due to the repelling force between like charges. Additionally, a charge that is "deficient" typically refers to a positive charge, but the terminology can be ambiguous without additional context.

Thus, the principle that electrons move toward a positive charge explains why this is the correct answer, as it aligns with the foundational understanding of electric charge interactions.
