When you sit indoors near a window on a sunny day your skin gets warm how does this happen?
f. the suns energy reaches your skin as radiation.
g. heat from the sun reaches your skin by conduction.
h. the suns energy is conducted to your skin by the glass
i. heat from the room is reflected from the windows onto your skin

Well, we know it's NOT I., because only LIGHT gets reflected.
We know it's NOT G., because conduction requires some pathway that actually CONNECTS to us, and a window can't "connect" to us.
H. is the same reason as G., and the problem didn't state that it touches or "connects" to us.
So that leaves only to A., and YES, it could reach our skin through radiation!
I hope I helped! =D
