Solution

The correct option is C

to increase effective length between object and image.


To test myopia or hypermetropia, opticians generally use plane mirror. This is generally because the distance between object and image becomes twice the distance between object and mirror. Hence to increase effective length between object and image optician's use plane mirror.
