  2. Front surface, back surface, and flat surface
  3. Front surface, mid surface, and back surface
  4. Front surface, back surface, and marginal surface
Explanation
Answer - A - Front surface, concave, and plane are the three types of dental mirrors. The front surface produces a clear mirror image with no distortions. The concave surface produces a magnified but slightly distorted image. The plane surface is less easily scratched than the front surface, but produces a double or “ghost” image.
