Hey there mate ;)!
Option B "Large face with painted white" is your answer.
Proof:-
• This is because, as more is the area of surface, more is the internal heat released. Therefore, it will have less heat.
• To make the best out of it, the white paint helps in reflecting back the heat rays. As there are more white, more heat rays are reflected back, thus, cooling the container very fast.
In other containers, some are black and small. This means that the container will heat up slowly and slowly, due to the presence of black colour.
