The power of an electric device can be calculated using the formula: Power (P) = Voltage (V) × Current (I). In this case, the voltage is given as 110 V and the current is given as 0.2 A.

To calculate the power of the bulb, we substitute these values in the equation: P = 110 V × 0.2 A. Now, let`s solve this equation.

P = 110 × 0.2 = 22

So, the power of the bulb is 22 watts (W).

Let`s analyze the options:

- Option 1: 0.22 W. This is not the correct answer as it is much smaller than the calculated power of 22 W.

- Option 2: 2.2 W. This is not the correct answer as it is still much smaller than the calculated power of 22 W.

- Option 3: 22 W. This is the correct answer as it matches the calculated power of 22 W.

- Option 4: 220 W. This is not the correct answer as it is much larger than the calculated power of 22 W.

Therefore, the correct answer is option 3: 22 W.
