b. V
When discussing the biological organization of an organism, the concept of tissue level refers to a group of cells that work together to perform a specific function. Mucous cells (I) are a type of cell found in certain tissues, thus they themselves do not represent the tissue level. The digestive system (II) refers to an organ system which includes various organs and tissues working together, which is a higher level of organization than tissue. Molecules (III) are a chemical level of organization, which is the level below cells. The stomach (IV) is an organ made up of tissues, so it represents the organ level, not tissue level.
