First, let's restate the statement in question to ensure clarity: The solar constant for the Earth is the amount of solar energy received at the Earth's distance from the Sun. 
Option under consideration: True. 
To evaluate this, recall that the solar constant is defined as the amount of solar energy received per unit area perpendicular to the Sun’s rays at a distance of one astronomical unit (AU) from the Sun, which is approximately the Earth-Sun distance. This value is conventionally taken as about 1361 watts per square meter (W/m^2), though historical measurements have placed it in a similar range. 
The key idea here is that the solar constant is not the energy received at the Earth's surface, nor is it the total energy emitted by the Sun; rather, it is the energy per unit area incident on a plane surface normal to the Sun’s rays at 1 AU. Since the Earth is roughly at 1 AU, the solar constant is indeed defined as the energy observed at that distance. 
Option: The statement says the solar constant is the energy received at Earth’s distance from the Sun. This aligns with the standard definition, because the Earth’s distance from the Sun corresponds to the reference distance for the solar constant, and the measurement is made at that distance, not at the Earth’s atmosphere or surface. 
Potential misconceptions: If someone confuses the solar constant with the solar irradiance at the Earth’s surface, they would be mistaken since atmospheric effects reduce the solar radiation that actually reaches the ground, and that value varies with time of day, weather, and latitude. If someone thinks the solar constant depends on Earth’s atmosphere, that is incorrect because it is defined at the top of the atmosphere, on a surface perpendicular to the Sun’s rays at 1 AU, before atmospheric attenuation. 
In summary, the statement captures the essence of the solar constant by tying it to the energy per unit area received at the Earth’s orbital distance from the Sun, independent of atmospheric losses or surface conditions. 
Therefore, the reasoning supports treating the assertion as correct, while keeping in mind the precise definition and common points of confusion discussed above.
