Light colored paving and cool roofs are terms referring to materials with
A . lower emissivity and lower albedo
B . lower emissivity and higher albedo
C . higher emissivity and lower albedo
D . higher emissivity and higher albedo

Answer: D

Explanation:

Light-colored paving and cool roofs refer to materials with higher emissivity and higher albedo.

Emissivity is the ability of a material to emit heat that it absorbs, while albedo is a measure of how much light that hits a surface is reflected without being absorbed. Materials with high emissivity can help reduce heat islands by releasing more of the heat they absorb, while those with high albedo can reflect more sunlight and thus stay cooler.
