Can someone points out which is the odd one? My guess was E, basis on the number to shapes in each square, only E contains odd number of figure while other contains even.

Can someone points out which is the odd one? My guess was E, basis on the number to shapes in each square, only E contains odd number of figure while other contains even.

Depending on interpretation, any of them is the odd one out:
A:
Only one with a shape with more than 4 sides.
B:
Only one with only one type of shape.
C:
Only one in which some shapes do not touch each other.
D:
Only one in which the total number of sides on all shapes is odd, assuming a circle is 1.
E:
Only one with an odd number of shapes (as stated in the question)
or: only one in which one shape completely overlaps with another.
Maybe, the answer is
D
Because
Count the sides. Only D has 5 sides, the others have 8.
My answer is:
E, because the circle is in front of two other shapes (the triangle and the square) whereas in all the others, each shape overlaps only one other at most.
12)in front of the question, this puzzle probably has a source other than yourself. Do you mind sharing it with us? – Rick Mar 28 '18 at 14:32
