Answer 1

The correct option is D good absorbers as well as good emitters

Black coloured objects have an interesting characteristic of absorbing heat as well as they can easily give off their heat energy. When they are exposed to sunlight they can heat up quickly. Hot black objects cool quickly when kept in a cool environment.
Hence, black coloured objects are a good absorber as well as a good emitter of heat.
