In order to determine spectator ions, we need to identify ions that do not participate in the chemical reaction and remain in solution unchanged. These ions are typically present in the same form on both the reactant and product sides of the equation.

In the given reaction, KS1U1P1+ and SOS1U1B14S1U1B0S1U1P12- are both present on both sides of the equation, indicating they are spectator ions. FeS1U1P12+ is ionized on the reactant side and incorporated into a different compound on the product side, so it is not a spectator ion. Likewise, MnS1U1P12+ is formed on the product side but not present on the reactant side, indicating it has participated in the reaction and is not a spectator ion.

Therefore, the only spectator ions are KS1U1P1+ and SOS1U1B14S1U1B0S1U1P12-, making choice C the correct answer.
