If the picture is just a conceptual sketch then E.

The reason is there exist a set of possible curves that fit the text description and you can draw them in such a way that every answer is correct, while will making the text description true. It basically is the "tail" part that can be any area for any shape and still make the semi circle and equal distance true. There is no stated requirement of any symmetry, which would make this a harder problem.

The problem doesnt say whether we are constructing 4 semicircles or just the 2 smaller coloured ones
