In the given reaction, Fe and K are both being oxidized while S is being reduced. Fe is going from +2 to 0 and K is going from 0 to +1, so each of these atoms is losing one electron. S is going from +6 in FeS to -2 in KS and gaining electrons, but we cannot determine how many are being gained as the reaction is unbalanced. Therefore, a total of 2 electrons are being transferred in the reaction. Hence, the correct choice is B) 2.
