{'common domestic power supply': [0, 0, 0, 1], 'correct parameters': [0, 0, 0, 1], 'india': [8, 1, 7, 13], 'hz': [0, 0, 4, 8]}
The correct parameters for the common domestic power supply in India are 220 V and 50 Hz.
Option 1 states that the domestic power supply in India is 220 V and 110 Hz, this is incorrect. The standard frequency for domestic power supply in India is 50 Hz, not 110 Hz.
Option 3 suggests that the voltage is 110 V and the frequency is 220 Hz, this is also incorrect. The standard voltage for domestic power supply in India is 220 V, not 110 V.
Option 4 states that the voltage is 110 V and the frequency is 50 Hz, this is also incorrect. The correct voltage for domestic power supply in India is 220 V, not 110 V.
Therefore, the correct answer is option 2.
