Answer:
My believe the answer is
A.) or B.)
Explanation:
Here is why I think A is the answer.
If we use the process of elimination, it would look like this,
a) Porque el aire tiene una temperatura menor que la de su cuerpo; por eso se propaga más rápido.
<em>This makes sense because we all know in winter the weather is very cold and freezing.</em>
b) Porque la temperatura de su cuerpo, siente el aire frio que entra por la ventana.
<em>I feel like this answer is the question, but it could also be an answer, sorry, I'm a little uncertain.</em>
c) Porque el calor de su cuerpo se propaga al medio ambiente, al ser la temperatura del niño mayor que la del aire exterior.
<em>This answer has nothing to do with the question, plus it is very false, our body heat is not enough to overcome the very cold temperature from outside.</em>
d) Porque la temperatura del aire es igual a la temperatura del cuerpo.
<em>This is false because again our body heat is not even compared to the freezing cold temperatures from the winter.</em>
