Answer:

only reason is true

Explanation:

Magnification of a concave lens or a convex mirror is always positive because they always form virtual and erect images. It can be negative or positive for a convex lens or a concave mirror.

Positive magnification for virtual images and negative magnification for real images is true only when a single optical device is used. When used as a combination, a virtual and inverted image may be formed. One such example is a compound microscope.
