Answer:
B. Chemical - Cellular - Tissue - Organ - Organ System - Organism
Explanation:
The human body's hierarchical system that builds from smallest to largest units is : Chemical - Cellular - Tissue - Organ - Organ System - Organism.
Chemicals such as oxygen and carbon dioxide are the basic unit of the human body that forms atoms and biomolecules which further undergo chemical reaction to form cell or cellular, which is a basic unit of all life. Cells then form their functional groups called tissues and then different tissues form an organ. Different organs work together and form an organ system such as the digestive system and respiratory system. All the organ systems then form a living organism or human.
Hence, the correct option is "B. Chemical - Cellular - Tissue - Organ - Organ System - Organism".
