Answer: 1 K W m^2
Explanation
On a clear day at noon, the intensity of the solar energy reaching the Earth's surface is approximately 1kW/m 2 (kilowatts per square meter),
which is equivalent to 1000 W/m².
Among the given options, the closest match is:
1 kW/m² (or 1 K W m-2 if expressed in kilowatts per square meter).
