Letters A , B , C and D are written on a cardboard as shown in the figure below. The cardboard is kept at a suitable distance behind a transparent empty glass of cylindrical shape. If the glass is now filled with water, one sees an inverted image of the pattern on the cardboard when looking through the glass. Ignoring magnification effects, the image would appear as

Correct answer

3

Step-by-step solution

A cylindrical lens produces erect and laterally inverted image. So, image appears as shown below.
