(B) The magnification $(m)$ of a mirror is defined as the ratio of the height of the image $(h_i)$ to the height of the object $(h_o)$,expressed as $m = h_i / h_o$.In a plane mirror,the image formed is always virtual,erect,and of the same size as the object.Since the height of the image is equal to the height of the object $(h_i = h_o)$,the magnification is $m = h_i / h_o = 1$.Additionally,the image is erect,so the magnification is positive,resulting in $m = +1$.
