Respuesta :
Here we can study the different temperatures of each one of the layers of the sun.
We will find that the way that the scientist can identify which layer are they studying is "The lowest temperatures are from the photosphere."
A brief description of the temperature of each layer is:
Center of the sun: about 15 million K
Radiative Zone: Â Goes from 7 million K to 2 million K.
Convection Zone: goes from 2 million K to 5800K
Photosphere: Is in average 5800 K , but there are sunspots with lower temperatures, of around 3800 K.
Chromosphere: goes from 4300 K to  8300 K
Corona: Around 2 million K.
So now we can analyze each of the options to see which ones make sense.
A) The highest temperatures are from the corona.
This is false, we can see that in the center and in the radiative zone we have larger temperatures than in the corona.
B) The lowest temperatures are from the photosphere.
While on average the temperature of the photosphere is larger than the smaller temperature of the chromosphere, in the photosphere we have the sunspots, and there we have the smallest temperatures in the whole sun, so this is true.
C) The lowest temperatures are from the core (or center).
Clearly false, there we have the larger temperatures.
D) Â The highest temperatures are from the radiative zone.
Again false, the larger temperatures are in the center.
So the only true option is "The lowest temperatures are from the photosphere."
