Earthworms are vital for soil formation as they ingest soil and organic material, digesting it and excreting it back into the soil in the form of castings. This process enriches the soil with nutrients and improves soil structure for better plant growth. Earthworms also increase soil porosity, allowing for better drainage and aeration for plant roots. Thus, choice A is the correct answer. Choices B and C are incorrect as they are not true statements about the role of earthworms in soil formation.
