The correct option is D Mosaic
Arthropod eyes are made up of repeating units of the ommatidia, each of which functions as a separate visual receptor. It contains a cluster of photoreceptor cells surrounded by support cells and pigment cells.
They form separate images. All of the small images formed by each ommatidium are grouped together to form a complete image. So that the final picture is a mosaic image comprising a number of pixels or small dots formed separately by each ommatidium. Such a vision is called a mosaic vision.
