Option C. "systemic lupus erythematosus"

Explanation:

Autoantibodies are defined as the antibodies that targets person's own tissues or organs. autoantibodies are produced by a person's immune system when it fails to differentiate between "self" and "non-self substances.

In patients with systemic lupus erythematosus, a diffuse autoantibody response takes place against person’s own DNA and proteins that results in different systemic diseases. Systemic lupus erythematosus may also affect the lungs,  central nervous system, skin, kidneys, heart, joints and other tissues, that causes tissue damage through antibody binding, lysis, inflammation, and complement recruitment.

Hence, the correct option is C.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
