Which of the following statements best expresses the law of conservation of electric charge for an isolated system?
(a) The algebraic sum of electric charges in a closed system can change if mass is converted to energy during nuclear reactions.
(b) The total positive charge in an isolated system must always equal the total negative charge present at every instant.
(c) The net electric charge of an isolated system remains constant even though charge can redistribute internally.
(d) The magnitude of the charge on every individual particle in the system cannot change during interactions.
