Of the 5 shapes in each tile, 2 pairs share a color and 1 is unique. For example, the first tile has the colors RGRYG, two reds, two greens, one yellow.
Consider then the first tile as GR. Looking at the rest of column 1 you see GY and GR. Col 2 has YR, GY, YR. Col 3 has YR, GR, ?. Columns share one color of doubles and have an ABA pattern for the others. So we know the mystery tile must have YR doubles. This leaves B, C, D, and E as answer choices.
Every tile has doubles for one shape and the rest are unique. On every row two of the tiles share a shape for their doubles and one is unique. This leaves answers C and E.
Every shape doubles in a row share a common point. The remaining point in the double is common for 2 tiles in a row and unique for one. In the 3rd row the two doubles have differing points so the 3rd tile must have its doubles similar to one the first 2 tiles. This leaves C as the only viable answer.
