Solution

The correct option is D (a) and (b) above.
Black coloured objects have an interesting characteristic of absorbing radiant heat well, i.e. when they are exposed to sunlight, they can heat up quickly. Also, they can easily give off their internal heat, i.e. a hot black object cools down quickly.
