- A 40-watt bulb is used for 6 hours every day.

- Calculating daily energy consumption: Power (in kW) = 40 watts = 0.04 kW; Daily use = 6 hours. Energy per day = 0.04 kW * 6 hours = 0.24 kWh.

- Total consumption for 30 days: 0.24 kWh/day * 30 days = 7.2 kWh.

- Electric units consumed are measured in kWh. Thus, the consumption is 7.2 units in 30 days.

- Option 1: 12 units - This implies much higher usage.

- Option 2: 1.2 units - This is too low.

- Option 3: 2.4 units - Also too low.

- Option 4: 7.2 units - Correct calculation for given usage.
