Which statement best describes the total electric charge of an isolated two-object system when the objects are brought into direct contact and then separated?
(a) Each object always ends with an equal net charge, regardless of their initial charges.
(b) The algebraic sum of the charges of the two objects remains the same before and after contact.
(c) The total positive charge increases because new positive charges are created during contact.
(d) Each object always ends with zero net charge because the charges cancel during contact.
