An object of size `2cm` is placed at a distance of `40cm` from a glass lens, close to the principal axis of the lens, and the lens forms an image of size `2cm`. What is the size of the image and what type of image is formed if the lens and the object, in the same arrangement, is immersed into water ? The refractive index of the lens `1.5`, and that of the water is `1.33`.

A

real image, upright and `4cm` in size.

B

virtual image, upright and `4cm` is size.

C

real image, upright and `2cm` in size.

D

virtual image, upright and `2cm` is size.
