In any process the total electric charge of an isolated system is conserved. This means:
ACharge can be created from nothing
BCharge cannot be created or destroyed — it can only be transferred from one object to another
CConservation only applies to positive charges
DConservation only applies at rest
Answer & Solution
Correct answer: B. Charge cannot be created or destroyed — it can only be transferred from one object to another
**Conservation of charge**: total charge of an isolated system is constant. Can be transferred (rubbing two materials, electrolysis) but never created or destroyed. As fundamental as conservation of energy or momentum.
