Three students measured the focal length of a convex lens using parallel rays from a distant object. All of the measured the distance between the lens and the inverted image on the screen.
(i) Student A saw a sharp image on the screen and labelled the distance as `f_(1)`
(ii) Student B saw a slightly larger blurred image on the screen and labelled the distance as `f_(2)`
(iii) Student C saw slightly smaller blurred image on the screen and labelled the distance as `f_(3)`
The relation between the three measurements would most likely be :

Options

A. `f_(1) = f_(2) = f_(3)`
B. `f_(1) lt f_(2) lt f_(3)`
C. `f_(3) lt f_(1) lt f_(2)`
D. `f_(1) lt f_(2)` and `f_(1) = f_(3)`
