• A. Mosaic
• B. Apposition
• C. Superposition
• D. Both a & b

Answer 1

The correct option is A Mosaic

Insects possess one pair of compound eyes and 1-3 simple eyes or ocelli on top of the head. But the eye produces mosaic vision similar to the crustaceans. Compound eyes are specially adapted to perceive the movements of objects. The insect compound eye is advanced structure because the number of ommatidia in insect eyes increases giving the eye sharpness of vision. Also the distance of vision increases in predatory insects and fast-flying insects.

So, the correct option is 'Mosaic'.
