Detailed Solution

  • Object distance and image distance are the same from a plane mirror.
  • The image of a person standing at a distance of 1 m in front of a mirror is formed at 1 m at the back of the mirror.
  • Therefore, the image will be 1 + 1 = 2 m away from the person.

Hence, 2m is the the correct response.
