Correct Answer: Option C — The order of resistors connected in the series string has no impact on the total resistance. The sum of the resistances is the total resistance of the circuit.

Series resistance is additive and governed by the commutative property of addition ($R_{total} = R_1 + R_2 + R_3$). The physical placement or order of resistors in a series string has no effect on the combined total resistance.
