This was a puzzle given "graduatetrader.com". I don't have its answer but it wasn't E as per them.
If you can find some pattern please help me.
I found one pattern by giving numbers to each arrows: 1 to 4 Then number way to select a pair for any fixed diagonal(or any pair lets say right bottom and top etc) is 4C2=6 So only remaining item will give a solution, but it isn't in options.
