magnification = length of camera /distance of object from the pinhile
Length of Camare = 0.3
Distance of object from pinhole = 3cm
M = 0.3/3 = 0.1

we now that Magnification = image hieght/ object height

We get M as 0.1
and we are looking for height of the image from the question.
and we are given 1.8m tall as the height of the object which is the man

so we substitute

0.1 = V /1.8 we have V = 1.8 × 0.1 = 0.18
Option A is very Correct
