B)reduction
C)both a and b
D)none of the above

Answer 1

Magnification is the ratio of enlargement and reduction of an image

Step-by-step explanation:

Magnification is the way of enlarging the apparent size of an object. When the magnification of an object is less than 1 it shows reduction in size while when it is greater than 1, it shows enlargement in size. Mathematically, it is given by :

`m=(size\ of\ image)/(size\ of\ object)`

i.e.
`m=(enlargement)/(reduction)`

Hence, the correct option is (c) " both a and b " i.e. " enlargement and reduction ".
