c
Resistance in a parallel circuit is the sum of the inverse of the resistances.
Each new bulb provides an additional path for current flow.

i'm an electric powered engineer and the answer is C, the total Resistance in parallel is smaller then the smallest parallel resistance. Use this formula. a million / R = a million / R1 + a million / R2 + a million / R3 +... desire this facilitates in the adventure that they are in sequence then the resistance promises up. C is sweet

C.
by adding another bulb you are increasing the number of paths the electricity can take, which in turn reduces resistance....i think.

c total resistance decreases.... the total resistance is smaller than any one resistance.
