Virtual Images and Retina

Assertion (A): A virtual image can't be caught on screen, yet we see a virtual image. We are obviously bringing it on to the screen, i.e. the retina.
Reason (R): The retina is a special type of screen present in the back of eye consisting of nerve fibre which can catch both real & virtual image.
 
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false

Solution:

Assertion (A) is true; virtual images cannot be projected onto a physical screen. Reason (R) is false; the retina, acting as a screen, can only detect real images formed by the eye's lens. Our brain interprets virtual images.
