1. The compound eye of cockroach consists of ommatidia, which form their separate image resulting into mosaic vision. The image so formed is incapable of distinct vision and blurred.

2. Nephridia are present as the excretory organs of earthworm which excrete urea out of the body.

3. Open circulatory system is present in cockroach where blood does not flow through distinct vessels but pumped through the haemocele.

4. Thyphlosole is present in the alimentary canal and increases the area of intestinal absorption.

5. The genitalia of cockroach is represented by phellomere of an insect that serves in copulation, oviposition, or stinging.

So, the correct option is 'A - 3, B - 5, C - 2, D - 1, E - 4'.
