A colour image is shown on the left. If the blue sky is painted black and the leaves are painted white, which is the CORRECT black and white image among the scaled options shown on the right? 
A
B
C
D
Repainting the sky black and the leaves white means every patch of blue in the original picture should turn into black, and every patch of green should turn into white, with the jagged boundary between them staying exactly where the leaves overlapped the sky in the original. The small gaps between the topmost leaf tips, and the larger strip of sky visible along the bottom of the picture, are what should end up black, everything else should turn white.
Only option B reproduces the exact shape and position of the original sky gaps in black, with the leaf regions correctly turned white.
So the correct answer is Option B.
