Answer:
(B) It uses more than one type of regular polygon.
Step-by-step explanation:
A tessellation of a flat surface is the tiling of the plane using one or more geometric figures having no gaps between them.
In order to make isogonal arrangements, a semi-regular tessellation use more than one type of regular polygon. There are nine semi-regular tessellation including the mirror image of one tessellation. These can be described by the vertex as well as the edge tessellations.
Hence, the semi-regular tessellation always use more than one type of regular polygon.
