Verified step by step guidance

Step 1: Understand the concept of levels of organization in the human body. These levels describe how the body is structured, starting from the smallest unit to the most complex. The levels are: Cell, Tissue, Organ, Organ System, and Organism.

Step 2: Define each level: - Cell: The basic structural and functional unit of life. - Tissue: A group of similar cells working together to perform a specific function. - Organ: A structure composed of multiple tissues that work together to perform a specific function. - Organ System: A group of organs that work together to perform complex functions. - Organism: The complete living being, composed of all organ systems working together.

Step 3: Arrange the levels in order from simplest to most complex. Start with the smallest unit (Cell) and progress to the most complex (Organism). The correct order is: Cell → Tissue → Organ → Organ System → Organism.

Step 4: Compare the given options to the correct order. Identify the option that matches the sequence Cell → Tissue → Organ → Organ System → Organism.

Step 5: Eliminate incorrect options by checking their sequence against the correct order. Select the option that accurately represents the progression from simplest to most complex.
