Solution

positive magnification means upright image with respect to object
negative magnification means inverted image with respect to object.
magnification greater than 1 means image size is larger than object size
and magnification less than 1 means image size is less than object size.

In case of convex mirror image is always reduced in size and upright, so 0<m<1
In case of concave mirror image is inverted-small, inverted large, upright-large, so m>1 and m<0
real image is only formed by concave mirror and possible results are inverted-small or inverted large image, So, m<0
Virtual image formed by concave mirror is upright-large, while virtual image formed by convex mirror are upright-small. So, m>0

So, correct match is
A-2,3
B-2,3
C-2,4
D-1,4
