Correct Answer - B
We use following equation to find height of the object.
`H_("image")//H_("object") = f//d`, where `d_(r)` is the distance between object and focal point of the mirror. Distance between object and focal point to the mirror x is `d_(fx) = 8f` and distance between object and focal point of the mirror y is `d_(fy) = 12f`. Let height of the object is h,
`H_("image")//h = 2f//8f`
`H_("image")x = h//4`
`H_("image")y//h = 2f//12f`
`H_("image")y = h//6`
`H_("image")//H_("image"Y) = 3//2`
