Solution

The correct option is D Statement 1 is correct but statement 2 is incorrect.
Light-coloured or white-coloured objects reflect more heat radiations than dark-coloured or black-coloured objects. This keeps them relatively colder than darker coloured objects.

Black coloured objects absorb more heat radiation than light coloured objects. This makes them hotter than the other colours.
Therefore, statement 1 is correct but statement 2 is incorrect.
