suppose you have focused on screen the image of candle flame placed at the farthest end of the laboratory table using a convex lens. If your teacher suggests you to focus the parallel rays of the sun, reaching your laboratory table, on the same screen what you are expected to do is to move the (a). lens slightly towards the screen (b). light slightly away from the screen

the answer of these question is :
in the case of candle flame , the object is placed beyond c , that means the image is formed or focused between c and f .in second case the object or sun is at infinity , so the image will be formed at focus.this means the distance between image and lens has decreased in the second case. either we have to move the screen towards the lens or the lens towards the screen
so option 1 is correct.
hope u got me
