Answer 1

The correct option is B

$\begin{array}{cc}\text{Blind spot}& \text{free of rod cell and cone cell}\\ \text{Yellow spot}& \text{centre of the retina}\\ \text{Ciliary muscles}& \text{shape of the lens}\end{array}$

Eye is a sense organ that responds to light. Light enters through the pupil and is focused by the cornea and the lens onto the retina. The shape of the lens can be changed by the ciliary muscles so that the image always comes to a sharp focus at the retina. Blind spot and yellow spot are the spots at the back of the eye. The blind spot is devoid of the ability for vision as it is free from rods and cones. Yellow spot is in the exact centre of the retina. It is specialised for seeing things with the highest clarity.
