C.
a black roof

D.
a white T-shirt
can someone please help me

Answer 1

A black color can absorb the most colors because black or other dark colors are more absorbent and white and light colors are more reflective.

So your answer is C. A black roof 

Answer 2

Black is not a color.  Black is the absence of visible light, so it's the absence
of all color.  Where you see black, it means no light is coming from there.  If
it's an object, then any light there was that hit that place got completely absorbed.
