Two problem figures have a specific common characteristic feature: both figures consist of a regular polygon where the number of internal dots is exactly equal to the number of sides of the polygon (e.g., a triangle with $3$ dots, a square with $4$ dots). Find the answer figure which shares this same characteristic feature.

1. A
   Figure A: A regular pentagon containing exactly $5$ internal dots
2. B
   Figure B: A regular hexagon containing exactly $4$ internal dots
3. C
   Figure C: A triangle containing exactly $2$ internal dots
4. D
   Figure D: A circle containing exactly $3$ internal dots
