Answer:
It depends on how the bulbs are connected.
Explanation:
if they are connected in series,
P=VI (we know V=IR)
P=IIR ( current in series will be same)
so power is proportional to Resistance so higher the resistance greater will be the power.
in this case answer is 750ohm one.
If bulbs are connected in parallel,
P=VI = VV/R ( since voltage will be same in paralle connection)
so power is inversely proportional to resistance.
in this case lower resistance will have hightest power so answer is 100 ohm.
