Solution
The correct option is A Nephridium
The earthworm has an elaborate system of excretion, which consists of small, coiled tubes with walls that are glandular and richly supplied with blood vessels. These coiled tubular excretory structures are known as nephridia and these are analogous to the kidney in humans. They occur in all segments of the body starting from the third segment downwards. So, the correct answer is option A.
