Text Solution

Verified by Experts
The correct answer is:
B
Step 1: The central region of the retina is known for its role in high acuity vision and is called the fovea or yellow spot.
Step 2: The yellow spot is so named because of the yellow pigment (xanthophyll) present in it, which helps in filtering UV light and enhances vision.
Step 3: The blind spot, in contrast, refers to the area of the retina where the optic nerve exits and contains no photoreceptors, hence no vision is possible in that area.
Conclusion: The correct answer is the yellow spot, which is the central part of the retina.
