The question requires that we find the number of sides for a regular polygon that will not form a regular tesselation.
To solve this we need to understand what a regular tessellation is;
A regular tessellation is a highly symmetric, edge-to-edge tiling made up of regular polygons, all of the same shape. There are only three regular tessellations: those made up of equilateral triangles, squares, or regular hexagons.
From the above, we can clearly see that there are three possible options for the number of sides for a regular tessellation.
1) Triangle(3sides)
2)square(four sides)
3)Hexagon ( six sides)
This implies that the odd one out, that is the number of sides that will not form a regular tessellation is
ANSWER: OPTION B
