A Correct answer
Explanation

Earthworms are called 'friends of farmers' because they burrow through the soil, creating channels that allow air and water to reach plant roots. Their digestive process breaks down organic matter, converting it into nutrient-rich castings (vermicast) that enhance soil fertility and structure. Leeches are parasitic, Sycon is a marine sponge, and Ascaris is an intestinal parasitic roundworm - none provide agricultural benefits.
