Answer: B.

but the resistance is lower in the parallel circuit.

Explanation:

A circuit with parallel connections has a lower total resistance than the resistors connected in series. This is consistent with conservation of charge. The power dissipated by each resistor is considerably higher in parallel than when connected in series to the same voltage source.
