First, let's calculate the area of the solar panel:

Area = length × width = 0.8 m × 0.5 m = 0.4 m²

Next, let's calculate the power output of the solar panel:

Power = current × voltage = 3.2 A × 15 V = 48 W

Now, we can calculate the intensity of sunlight on the solar panel:

Intensity = Power / Area = 48 W / 0.4 m² = 120 W/m²

Finally, we can calculate the efficiency of the solar panel:

Efficiency = (Power output / Intensity of sunlight) × 100% = (48 W / 120 W) × 100% = 40%

Therefore, the efficiency of the solar panel is 40%. However, since none of the answer choices match this result, we need to round it to the nearest option, which is C (12%).
