Well the soil classification is usually done on the basis of particle sizes and composition of soil.
Clay usually consists of particles less than 0.075 mm in size. It is a sticky soil and shows great changes in volume with variation in its water contact. It also shows considerable strength when air dried.
Silt has larger particles than clay and are mainly inorganic in nature. The particle size is less than 0.075mm and exhibits slightly plastic or non plastic behaviour.
Humus is soil consisting of dead and decaying organic matter. It is mainly organic in content but some inorganic particles may be mixed in it. The top soil in a tropical forest may be considered as humus.
Sand is the largest particle in soil among the options provided. Particles in soil are categorized into three groups: sand, silt, and clay, with sand having the largest particle size. Humus, though a soil component, is not a soil particle but decomposed organic material.
The largest particle in soil, out of the options given, is sand. In soils, particles are categorized into three main groups according to their sizes: sand, silt, and clay. Sand has the largest particles, typically between 0.05mm and 2mm in diameter. On the other hand, silt particles are smaller than sand, typically between 0.002mm and 0.05mm, and clay has the smallest, less than 0.002mm. Humus, another component of soil but not a soil particle, is decomposed organic material that contributes to the nutrient content of the soil.

Mucus protects the lining of the stomach from acidic gastric juices.
Hydrochloric acid (HCl), lipase, and pepsin come together specifically in gastric juice. Its primary purpose is to render ingested bacteria inactive, preventing infectious pathogens from entering the intestine.
Squamous epithelium, like the skin, is found in the mucosa of the mouth and the esophagus and is thought to serve as a barrier against infection.
Gastric juice makes food particles soluble, starts digestion (especially of proteins), and transforms the contents of the stomach into a semiliquid material termed chyme, laying the groundwork for subsequent small intestine digestion.
Therefore, Mucus protects the lining of the stomach from acidic gastric juices.
