P = V²/R
When both the bulbs are given same voltage
R ∝ 1/P
Hence, resistance will be more for the given which is dissipating less power.
Resistance is more for 25 Watt bulb.

Answer:
The answer is 25 watt bulb.
Explanation:
The formula for power is P = V²/R
Hence, Power is inversely proportional to the resistance when voltage is constant. In the above query, the voltage given should be the same.
The resistance of 25 watt bulb will be more as compared to the 100 watt bulb because it is of less power.
