Assertion (A): Iris of the eye contains rods and cones which transmits electric signal to brain through optic nerve.
Reason (R): Rods sense colour of object and cone sense intensity of light.
(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:
Both Assertion (A) and Reason (R) are false. Rods and cones are located in the retina, not the iris. Rods detect light intensity (dim light), and cones detect color (bright light).
