Solution

The correct option is C $- 0.2$

Given:
Height of the image, $h_{i} = - 2 c m$ (inverted image);
Height of the object, $h_{o} = 10 c m$ (erect object);
Magnification $(m) = \frac{height of image}{height of object}$ = $\frac{h_{i}}{h_{o}}$
$\Rightarrow \frac{- 2}{10} = \frac{- 1}{5} = - 0.2$ .
The negative sign in magnification shows that the image formed is real.
