C is correct
Decrease
yes the answer is cTHE TOTAL RESISTANCE DECREASES
Yes, that's correct! When light bulbs are wired in parallel, the total resistance decreases as more bulbs are added. This is because the current can flow through each bulb simultaneously, rather than having to overcome the resistance of just one bulb.
