Solution

The correct option is A Negative
We know,
Magnification(M) $= \frac{h e i g h t o f i m a g e (h_{i})}{h e i g h t o f o b j e c t (h_{o})}$
Here, image is inverted so according to sign convention $h e i g h t o f i m a g e (h_{i})$ will be negative while object height will be positive.
Hence, the magnification of a mirror is negative.
