The correct hierarchical order with respect to the level of organization in animals is
The correct option is B Cell, tissue, organ, organ system
The biological levels of organization of living things arranged from the simplest to most complex i.e., organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere. All living things are made of cells as the cell itself is the smallest fundamental unit of structure and function in living organisms. Cells combine to make tissues, which are groups of similar cells carrying out similar or related functions. Organs are collections of tissues grouped together performing a common function. An organ system is a highest level of organization that consists of functionally related organs. Hence option B is correct.
