Show answer and explanation

Correct answer: (A) Option A in the figure

Explanation

Each region must carry the colour of the sets that overlap there: Yellow with Magenta only is Red, Yellow with Cyan only is Green, Magenta with Cyan only is Blue and all three is Black. In option A the region of Yellow and Magenta only is R, the Yellow and Cyan only regions are G, and the regions where all three overlap are K. In B the Yellow and Magenta only region is labelled Bl, in C a region where all three overlap is labelled Bl, and in D several overlaps are labelled with the wrong colours.
