Explanation:
Electric power is given by P = VI. Hence, we can calculate the resistance using Ohm's Law as follows:
R = V^2/P
For the 40W bulb:
Resistance R1 = (200V)^2/40W = 1000 ohms
For the 100W bulb:
Resistance R2 = (200V)^2/100W = 400 ohms
Therefore, the resistance of the 40W bulb is more than the 100W bulb.
Hence, the correct option is B.
